Gaming establishments typically strive to provide a player with a satisfying experience while ensuring that the gaming establishment has the best possible chance to maximize revenue and profit from each player. Creating a satisfying experience can be assisted by making gaming convenient and easy for the player. Maximizing revenue may be assisted by reducing fraud or cheating. Described below are various embodiments of the inventive subject matter hereof that may, among other things, assist in improving a player's experience in a gaming establishment and also in enhancing a gaming establishment's profit by reducing fraud or cheating or by other means.
In the following detailed description of the embodiments of the inventive subject matter, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments in which the inventive subject matter may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the inventive subject matter, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present inventive subject matter. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present inventive subject matter is defined only by the appended claims.
Referring now to
As used herein, the term casino game encompasses, without limitation, slot machines, video poker machines, roulette tables, poker tables, craps tables and any other game of chance offered by a gaming establishment wherein for example the game qualifies as regulated and/or licensed gaming equipment. The term gaming establishment refers to an establishment that offers casino gaming experiences to its patrons and, in one example embodiment, is licensed by a gaming regulatory authority to provide such gaming experiences.
As illustrated in
Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to automatically identify individual items. There are several methods of identifying objects using RFID tags, such as tags 108. One of the most common is to store a serial number that identifies an item, thing, or person (such as an individual carrying an RFID tag 108), and perhaps other information, on a microchip that is attached to an antenna (the chip and the antenna together are called an RFID transponder or an RFID tag). The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves returned from the RFID tag into a form that can then be passed on to, for example the system 120, that can make use of it. While it depends on the particular RFID tag and the application, one example embodiment of a RFID tag 108 carries about 2 KB of data—enough to store some basic information about the item or person it represents.
As described in various configurations below, an RFID system such as system 100 may comprise a RFID tag 108, which is made up of a microchip with, for example, a coiled antenna, and an interrogator or reader with an antenna, referred to herein in some instances as a reader component 106 generally, or more specifically as may be provided in some embodiments as a reader unit 204 and antenna 202. Reader unit 204 may include an integral or co-located antenna, or it may be deployed with one or remote antennas deployed at some distance from the unit 204. Remote antennas may be coupled to the reader unit 204 with a wireline connection. The reader 204 generates electromagnetic waves from the antenna 204 that form a magnetic field when they “couple” with the antenna on the RFID tag. According to one example embodiment, system 100 or other embodiments herein below described use passive tags that have no battery. These passive tags draw power from the reader, which sends out electromagnetic waves that induce a current in the tag's antenna. The RFID tag draws power from this current and uses it to power the microchip's circuits. The chip then modulates the waves that the tag sends back to the reader and the reader converts the new waves into digital data. Most passive RFID tags simply reflect back waves from the reader. Energy harvesting, on the other hand, is a technique in which energy from the reader is gathered by the tag, stored momentarily, and transmitted back at a different frequency.
According to another example embodiment of the RFID tags 108, there are provided active RFID tags that have a battery, which is used to run the microchip's circuitry and to broadcast a signal to a reader (for example like the way a cell phone transmits signals to a base station). Semi-passive tags can also be used in the embodiments herein, and use a battery to run the chip's circuitry, but communicate by drawing power from the reader. Active and semi-passive tags are useful for tracking items that need to be scanned over long ranges, but they cost more than passive tags. The read range of passive tags may not be as far as active tags, for example for some example technology, less than ten feet as opposed to one-hundred (100) feet or more for active tags. More particularly, the read range of passive tags depends on many factors: the frequency of operation, the power of the reader, interference from metal objects or other RF devices. In general, low-frequency tags are read from a foot or less. High frequency tags are read from about three feet and UHF tags are read from 10 to 20 feet. Where longer ranges are needed, active tags use batteries to boost read ranges to 300 feet or more.
Radio frequency identification in system 100 does not require line of sight. RFID tags can be read as long as they are within range of a reader. Radio waves travel through most non-metallic materials, allowing RFID tags or the readers to be embedded in packaging or encased in protective plastic for weather-proofing and greater durability. Or, in the alternative, the reader component 106 can be mounted in a housing provided that the radio waves can traverse the housing, either by going through a wall, window or opening in the housing. However, reading an RFID through a metallic barrier can be more difficult.
RFID tags and readers have to be tuned to the same frequency to communicate. RFID systems can use many different frequencies, but generally the most common are low- (around 125 KHz), high- (13.56 MHz) and ultra-high frequency, or UHF (850-900 MHz). Microwave (2.45 GHz) is also used in some applications. Different frequencies have different characteristics that make them more useful for different applications. For instance, low-frequency tags are cheaper than ultra high frequency (UHF) tags, use less power and are better able to penetrate non-metallic substances. UHF frequencies typically offer better range and can transfer data faster. But they use more power and are less likely to pass through materials. And because they tend to be more “directed,” they may require a clear path between the tag and reader.
System 100 and other embodiments disclosed herein may be implemented with read-write or read-only RFID tags 108. With read-write chips, an application can add information to the tag or write over existing information when the tag is within range of a reader, or interrogator. Some read-only microchips have information stored on them during the manufacturing process. The information on such chips can never be changed. Another option is to use electrically erasable programmable read-only memory, or EEPROM. With EEPROM, the data can be overwritten using a special electronic process.
It is noted that one problem encountered with RFID is the signal from one reader can interfere with the signal from another where coverage overlaps. This is called reader collision. One way to avoid the problem is to use a technique called time division multiple access, or TDMA. In simple terms, the readers are instructed to read at different times, rather than both trying to read at the same time. This ensures that they don't interfere with each other. But it means any RFID tag in an area where two readers overlap will be read twice. Accordingly, in one example embodiment of the systems and methods described hereinabove, the system or method is operated so that if one reader reads a tag another reader does not read it again. Another problem readers have is reading a lot of RFID tags in the same field. Tag collision occurs when more than one chip reflects back a signal at the same time, confusing the reader. Different vendors of RFID technology have developed different systems for having the tags respond to the reader one at a time. Since they can be read in milliseconds, it appears that all the tags are being read simultaneously.

Referring now to
Reading devices 1730 may be positioned, for example, underneath the gaming table surface 1742 of table game 1740 near an area that a player may place a bet using the betting articles, to enable the devices 1730 to detect the presence of the betting articles, and, for example, the identification and value of the article by reading the data stored therein. Reading devices 1730 may also be positioned in other areas of the table game 1740, for example to read the RFID tags in betting articles collected by the dealer into or paid by the dealer out of a chip tray, sometimes also referred to as a chip rack or bank. Reading devices 1750 may be positioned, for example, near an acceptor 1764 of the gaming machine 1760, to enable the devices 1750 to detect the presence of the betting articles 1710 placed in the acceptor 1764, and, for example, the identification and value of the article by reading the data stored therein. Reading devices 1750 may also be positioned in other areas of the gaming machine 1760, for example to read the RFID tags in betting articles in a hopper 1766, from which they can be dispensed, or alternatively to a drop box (not shown) to be collected. Reading devices 1750 may also be positioned to read RFID tags of betting articles that may be dispensed by the gaming machine 1760. Accordingly, gaming machine 1760 is adapted to receive betting articles 1710 and to dispense them in the same manner as coins or tokens or other betting articles used in the gaming machine wherein the articles are placed in an acceptor and counted to create credits on the machine, for example.
According to still another example embodiment, the method and apparatus may provide for shielding the RFID reading devices (for example 1730 or 1750) to ensure that the only RFID signals it detects are those coming from the betting article path (for example 1767 in
In either the case of the reading devices 1730 or 1750, the reading devices may be connected to a local computing platform 1735 or 1755 located at or near the table game 1740 or gaming machine 1760, such that the local computing platforms can receive information from the RFID tags and perform any desired functions, such as to provide counts or indications to dealers or players or other personnel. One or more further computing systems 1770 may also be provided, and are adapted to receive data pertaining to the betting articles 1710, wherein the data pertaining to the articles is at least in part determined using the one or more items of data associated with an identification tag. Systems 1770 may be located distant from the table games or gaming machines, for example in a computer center in a casino or other gaming establishment, or in any other location. In one embodiment, the local computing platforms are connected, for example through wired or wireless network, to the computing systems 1770 and pass information about betting articles 1710 to the computing systems 1770.
Thus, according these embodiments, the same betting articles, typically casino chips, may be used both to play a table game and also to play a gaming machine. This dual use of the betting articles such as chips thus provides a player with convenience, and also increases the chances that a player of one type of game may stop and play the other type of game, thus enhancing the player's range of experience and potentially keeping the player in the gaming establishment longer than otherwise may be the case. In addition, the ability to read an identification from the betting articles may assist in cheating or fraud reduction, as betting articles may tracked and only accepted or credited if properly registered, as may be implemented using software on, for example, system 1770, to register and track the betting articles. Other information about the use of the betting articles may also be determined where their use is tracked by system 1770 or by other means.
According to still another embodiment, the plurality of betting articles 1710 are located on the premise of a first gaming establishment, and in another embodiment, they are located on at least two different gaming establishments. Thus, accordingly, the same betting articles may be used at multiple different gaming establishments, which may or may not be owned entirely by or substantially by the same entities. In addition, accordingly, the computing system 1770 may be adapted to track betting articles across multiple establishments. For instance, all betting articles 1710 may be registered and tracked using a common computing platform or data repository whether or not the articles are issued or honored by the same or different gaming establishments under the same or different control.
According to another example embodiment 1800 of the inventive subject matter there is provided a method wherein one or more betting articles, for example chips, are distributed 1810 to a player for use in a casino, wherein the one or more chips have a monetary value, and wherein each of the one or more chips include a radio frequency identification tag device associated therewith. The one or more of the chips are accepted 1820 from a player at a table game wherein chips are used to place bets, and information is read 1830 about the one or more chips from the tag device while the one or more chips are located at the table game. Further, the one or more chips may also be accepted 1840 in a gaming machine, wherein the gaming machine reads 1850 information about the one or more chips from the associated tag devices, and the gaming machine credits 1860 the player with an amount determined at least in part using the information read from the tag device.
According to one example embodiment, the betting articles may have a monetary value. In an alternative embodiment, however, the gaming articles may have no monetary value, for example promotional gaming chips. Such betting articles may not be redeemable for currency but would be valid for placing wagers at a table game or at a gaming machine. In another embodiment, there may be three types of credit tracked on a gaming machine: cashable credits redeemable for currency (usually comes from money inserted by the player or from winnings achieved by the player), non-restricted promotional credits redeemable for currency (credits given to the player by the casino typically as part of a marketing program), and restricted promotional credits not redeemable for currency (credits given to the player by the casino or gaming establishment that must be wagered). Both non-restricted and restricted credits can only be inserted into the gaming machine at this time either via a ticket/coupon accepted via the bill acceptor and validated with a cashless wagering system or via an electronic download from a player account established with the gaming establishment and transmitted to the gaming machine via a cashless wagering system.
According to one example embodiment, there may also be accepted betting articles at a game with the associated RFID tag containing information related to which type of credit that betting article represents, thus providing the gaming establishments with another method of inserting promotional credit into a gaming machine. Also, like tickets and player account transfers, one embodiment may require that the promotional credit only be accepted if a player card is present at the gaming machine/table (allowing the system to monitor which players are responsive to different promotions) or if a specific player card is inserted at the gaming machine/table (allowing promotions to only be redeemed by a specific patron).
According to another example embodiment, there is provided a bonusing method and system. In one example, a bonusing system/method might award a “lucky betting article (e.g. chip)” bonus. To do so, for example, a random number is generated that identifies one or more of the betting articles by a unique identifier, such as a serial number. The system may run the bonus across the entire establishment, or use a subset of the entire floor as a group of gaming machines participating in the lucky betting article game. The system may then monitor the betting article acceptors for all games participating in the bonus pool. And when the randomly selected betting article is wagered, the gaming machine where the wager was placed may be awarded a bonus paid to the player at the gaming machine. In one example embodiment, these may be progressive bonus awards that would increase over time. According to one example embodiment, the system/method may randomly select a betting article identifier (e.g. serial number stored in the RFID tag) from the total set of betting articles in the gaming establishment system, which may be segregated by denomination, promotional betting articles, or other means.
According to one example embodiment, the lucky betting article may be implemented at table games such that, for example, the table game may provide the dealer with some form of notification that it detects the ‘lucky betting article’ at a particular betting spot and the amount of the bonus to be paid. The notification may take the form of a message displayed on a video screen at the gaming table, the betting spot could light up, or there could be an audible indication, either alone or in combination with each other. The dealer may then pay the bonus in betting articles in addition to any wins the player may have achieved with that bet.
According to other example embodiments of the methods of the inventive subject matter, at least one chip is accepted from a player at a table game wherein the chip is used to place a bet and wherein the chip include a radio frequency identification tag device associated therewith. Information is read from the chip from the tag device while the chip is located at the table game. At a later time, the at least one chip is accepted in a gaming machine, wherein the gaming machine reads information about the at least one chip from the associated tag device, and the gaming machine credits the player with an amount determined at least in part using the information read from the tag device.
According to another example embodiment, at least one chip is accepted from a first player at a table game wherein the chip is used to place a bet and wherein the chip include a radio frequency identification tag device associated therewith. Information about the chip is read from the tag device while the chip is located at the table game. At a later time the at least one chip is provided to a second, different player, and the second different player uses the at least one chip in a gaming machine. The gaming machine reads information about the at least one chip from the associated tag device, and the gaming machine credits the player with an amount determined at least in part using the information read from the tag device.
