Definitions
- the present invention refers to terminal hardware having the capability of, indifferently, processing two types of portable data elements in the form of a card. More specifically, it refers to the reading of the information contained on inductive cards of the type described in Brazilian patent documents PI 7804885 and PI 9201380. as well as on smart cards with contact pads, i.e. "chip cards” and furthermore, to the recording of new information on both types of cards, without any other manipulation but the manual insertion and withdrawal of said cards by the user.
- Fig. 1-a shows a card of this type which is divided lengthwise into three areas, namely, central region 11 containing the credit cells, and two end areas 12 and 12' where there are no cells since these are intended for the handling of the card by the user during the insertion or withdrawal from the card reading device ("reading head").
- four cells 13, 14, 15 and 16, located at the corners of said central area are used to identify the position and validity of the card, according to the previously mentioned patent document PI 9201380.
- the reading head comprises two dissimilar and complementary portions, the lower one containing the active elements for the exchange of information with the cards, namely, the sensors 41 arranged in a rectangular matrix for reading/burning-out the debit cell of the inductive cards, and the inductors 60, 70, comprising the coils 65 and 75 coils wound around magnetic cores, magnetically coupled to the pick-up coils of the smart cards.
- the upper part of the reading head contains only magnetic pole pieces 43.
- the first one a plate or slab that closes the magnetic circuits of sensors 41 and the other two, closing the magnetic circuits of inductors 60 and 70, all assembled on a rigid base of thermoplastic material 48, to which the first portion, the lower one, is attached by means of four screws 45 that act as lead-pins during the separation of the two portions during card insertion, complemented by two helicoidal springs 44 having the purpose of mutually compressing said two portions.
- Figure 1 -b shows, only for illustration purposes, a set of contact pads meeting the international standard ISO 7816-2.
- Each pad has the minimum dimension of 1.7 x 2 millimeters and, as shown, the 8 contact pads are posicioned in rows 18 and 19 along the opposite sides of a square having sides measuring 7.6 mm.
- row 18 is located within the handling portion of the card, remaining outside the area occupied by the sensors for reading/burning-out of the inductive credit cells. This does not happen with the row 19, in which the pads are placed inside the central area 11 of the inductive card occupied by credit cells.
- the present invention has the main aim of providing a reading device - reading head - able to exchange information with cards having different thicknesses and free from friction wear during the insertion and withdrawal of the card.
- Another aim consists of the provision of means for supplying power and exchanging information with smart cards provided with contact pads - chip cards - which do not interfere with the sensing coils used for the reading 96/17318 5 PC17BR95/00059
- said reading head comprises mutual elastic compression means between said portions, so as to accept cards having different thicknesses.
- the information transfer between the reading head and the card, as well as the supply of power for the card's active circuitry are achieved by means of conduting pins provided on said second portion of the reading head which touch the contact pads provided on the smart card only at the final part of said card insertion.
- Figure 1 shows the distribution of active and inactive areas on inductive debit cards and of smart cards having contact pads - chip card - according to known techniques; in the case of figure 1 -b, the position of the pads meets international standard 1S07816-2.

- four identifying elements, 21 , 22, 23, 24, are provided which are located in the same position as elements 13, 14, 15, 16 of the inductive cards (fig.1 -a) and serving, like the latter, for the card's correct position and validity identification.
- the reading device comprises two different portions, 80 and 140; the former containing a plurality of sensors 83 arranged in a square matrix for the exchange of information with the inductive debit card, the internal faces of the magnetic cores being aligned with the internal plane of the insulating block 82 supporting said sensors, forming a first level surface, on which the card slides when inserted or withdrawn from the device.
- the magnetic circuit of said sensors is completed by the magnetic plate 142, incorporated in the upper portion 140 of the reading head which is pressed against said first surface by means of a spring action not shown in the figure.
- the aforesaid portion 140 moves vertically along guide-pins 95 which fit into through holes 143.
- lower portion 80 is provided with two U- shaped metallic frames having square corners, 84 and 85. the sides of the "U” fitting slidingly into longitudinal channels provided at both sides of said sensor matrix.
- the frame 85 is slightly wider and substantially longer than frame 84 so that the latter fits slidingly into frame 85.
- the unidirectionalal retaining grip 86 is fixed on the transverse portion of the internal U-frame 84.
- a longitudinal rod 88 is fixed; this rod points toward the front of the reading head, left side in Fig. 3.
- a hole 87 is provided in the transverse portion of frame 84, through which said rod passes loosely, its front end being fitted with a flat-faced circular stop 89, behind which is a second flat cylindrical enlargement 89'.
- the left and right sides of external frame 85 are provided with two substantially rectangular tabs 94 projecting upward, i. e., ortho- gonally to the main plane of the reading head.
- the sides of the internal frame are also provided with tabs 93 in the same positions with the same orientation and height of the preceding ones having, however, a trapezoidal shape where the slope is directed towards the front of the reading head.
- the upper portion 140 of the reading head has a substantially retangular shape, the central part of which is occupied by the magnetic plate 142. and having on its sides lour rods 144 at right angles to the length of said reading head; said rods rest on the top edges of said tabs 93 and 94 when there is no card inserted in the reading head.
- the relative positions of the magnetic plate 142 and rods 144, as well as the height of tabs 93 and 94, are provided so as to make the aperture for the card, between the lower surface of plate 142 and said face 82, substantially larger than the thickness of the chip-card, for example 1.5 to 2 millimeters.
- Oblo ⁇ c holes are 145 placed on the lateral border of portion 140. in the positions of tabs 93, 94, but substantially larger than said tabs, to allow the free vertical movement of said portion, without any interference between tabs 93 and 94 and the body proper of portion 140.
- the interconnection with contact pad rows 18 and 19 on the chip card is achieved by means of pins 162, assembled on insulating block 161.
- the upper ends 164 of said conductor pins are electrically connected through flexible wires, to the electronic circuitry of the reading head.
- the lower ends of these pins also stay away from plane 82 when there is no card in the reading head, only approaching the card at the end of the insertion operation.
- block 161 has two posts 163 which rest on contours 151 of internal brackets 150 and external brackets 152, both having a rectangular "U" shape, the former fixed by means of bolts (not shown) passing through holes 153 and fastened to the transverse portion of moveable frame 84 and the latter also fixed in the same manner on the cross part of frame 85 by bolts or rivets (not shown) which pass through holes 154 and 155.
- Said block 161 is provided with guiding holes 162 which fit into guiding pins, not shown in the figure, fixed on the upper face of portion 140 to allow only vertical movement of assembly 160.
- the lower portion of contact pins 162 slide into hole rows 146 and 146' posicioned in said upper part 140 in accordance with the contact pads in the chip card.
- the lower ends of these pins remain slightly withdrawn into said hoies. thus avoiding any damage to the card surface during its insertion.
- Figure 4-d shows the termination of the card insertion where it can be seen that tabs 94 have been completely displaced from the positions of rods 144 which, not being supported any more, come down toward part 80 of the head, in the direction indicated by the arrows, allowing portion 140 of the reading head to approach the card due to the spring action (not shown) which provides the mutual compression of the two parts cf said reading head.
- Figure 4-e shows the moment at which the cross piece of frame 84 touches the back face of enlargement 89' on rod 88; from this point on, frame 85 begins to be pulled in conjunction with frame 84, resulting from this movement the positioning of rectangular tabs 94 under the already lifted rods 144. From this point on, the horizontal movements of said frames 84 and 85
- FIG. 7 shows the operation of the unidirectional retaining grip. As shown in figure 7-a, this device comprises a cylinder 172 which is pressed in the direction of the entrance slot by spring 173 which pushes the shoe 174.
- Figures 5 and 6 show, in the form of block diagrams, the electronic hardware of the invention in two preferred embodiments, the first for reading and recording credits on cards having either an inductive technology or smart cards, needing just the execution order to carry out the requested operation.
- the hardware has only the function executing blocks, the timing and sequencing being carried out by an external processor
- said hardware comprises reading head 125 which is analogous to the ones described in Brazilian patents PI 9204434 and PI 9300949 as to the inductive technology, in addition to a set of contacts and corresponding interface for processing chip cards.
- the inductive sensors are connected to the crossing points of column conductors 126 and line conductors 127, so as to constitute a matrix, switchable by means of a selection of a line and of a column, according to the principles described in Brazilian patents PI 9203968 and PI 9302569
- the operation of the head is controlled by microcontroller 1 12, the control program being stored in ROM 1 13.
- the head checks of the type of card inserted into reading head 125 and carries out the functions requested via interface RS232, block 1 18, connected to the microcontroller by means of bus 1 17, delivering the response to the request also through said interface 1 18.
- each inductive cell is directed by the microcontroller which places the multiplexed address thorugh bus 1 15 in circtuits 121 and 122, the former enabling one of the column drivers of driver set 124, and the latter completing the selection by turning on one of the line switches of line set 123, according to the operating principles described in aforesaid PI 9203968.
- the enabled oscillator applies an alternate current to the sensing coil, its value being monitored through a condition detector 1 14 which informs the microcontroller about the status of the cell.
- Figure 5 also shows blocks 1 10, a linear voltage regulator and block 1 11 , the PWM circuit, or switching voltage regulator, to provide the working voltages to the components and circuits. Also shown is bus 1 16 for the connection of microcontroller 1 12 to interface 1 19 for the smart card, via contacts 120. The need or not for interface 1 19 is defined by the technology used in the smart cards.
- figure 6 shows the hardware as being a set of blocks whose timing functions are supplied by an external processor via bus 130.
- the system needs to know when and what type of card has been inserted into the reading head.
- the system makes use of sensing coils placed at the four corners of the inductive sensing matrix comprised in portion 80 of the reading head (shown in bold trace in Fig. 3), as taught by Brazilian patent PI 9201380. If said coils detect the presence of identifying cells 13... 16, as mentioned in said paten; document, the inserted card will be interpreted as being inductive, and the processing will branch into the corresponding routine.
- the presence of a smart card may be detected by monitoring the electrical current existing at the bus connected to the contact pins 164 (or 120 in figures 5 and 6), or by any other identifying means defined from the features of the integrated circuits enclosed in the card. In this case, the processing will be switched to the subroutine suitable to smart cards.
- the card reader checks the conditions of the cells in positions 15 and 16 so as to ensure the presence of an inductive card, according to the above mentioned PI 9201380. If so, it branches into the routine of inductive card mode. If the conditions of the cells do not correspond to the standard defined for the inductive card, it will show a suitable message in the display;
- the card reader starts to check the eventual presence of a smart card by monitoring the current on the contacts or through any other suitable process. Once the presence of a smart card has been confirmed, the processing is branched to the corresponding routine. If the presence of a smart card is not confirmed, a suitable message will be shown on the display and a new card presence check out cycle will be started.
- inductive cells may be added on smart cards in the four positions reserved for identifying cells, but coded differently from those used on inductive cards so as to allow for a quicker identification of the smart card
- chipcard shown on Fig. 2 where it can be seen that on each longitudinal border of the card the identifying cells are in opposite conditions, i. e., adjacent to border 31 we have cell 21 in a shorted condition and cell 22 in an open condition, while adjacent to border 32 the cell 23 is open and the cell 24 is shorted.
- the inductive debit card shown in Fig 1 -a has both open cells 13, 16 along one border and two shorted cells 14, 15 along the other border.
- inductive cells may be placed in the central portion provided on smart cards to provide indelible and permanent identification of the bearer, allowing him to access specific functions.
