SYSTEM FOR PROCESSING IC CARD WITH
BACKGROUND OF THE INVENTION 5
1. Field of the Invention:
The present invention relates to a card processing system which uses IC cards (integrated circuit cards). More particularly, it relates to a system for processing IC cards with a display function which is well suited to visually display guidance information effective for a card user on a display equipment such as of liquid crystal built in each IC card.
2. Description of the Prior Art: 15 An IC card can store a comparatively large number
of information items therein, and has excellent features for keeping secrecy. Heretofore, various card processing systems utilizing these features of the IC cards and performing the identification of individuals, the man- 2Q agement of the specified information of the individuals and the attendant information processes have been constructed.
Such card processing systems and apparatuses are described in NIKKEI ELECTRONICS dated Dec. 2, 25 1985, pp. 275-292, and the same bulletin dated Dec. 16, 1985, pp. 249-262.
Now, the card processing system in a prior art will be outlined as to a case of application to hospital management.
In a hospital, the IC card processing system is utilized for the systems of outpatient receipt management, anamnesis management, inspection data management, account management, etc. More specifically, a patient bears an IC card for his/her exclusive use and submits 35 the IC card to a reception window. In the reception window, the IC card is inserted into an IC card reader/writer installed there, whereby the contents of the IC card are read to identify the patient. In a case where the patient is a new patient for the first medical examina- 40 tion, his/her condition, the desired contents of medical examination and treatment, etc. are written into the IC card in a predetermined format. On the other hand, in case of medical re-examination, the condition of a disease, the expected contents of medical examination and 45 treatment, etc. at the current time are written into the IC card in a predetermined format by reference to the previous contents of medical examination and treatment stored in the IC card.
Subsequently, the patient bears the IC card and goes 50 to the reception window of a designated department, to which he/she submits the IC card. In the departmental window, the IC card is subjected to a receipt process by the use of a card reader/writer installed in this window, whereupon information items on the examined and 55 treated contents, the prescriptions of medicines, the necessity of any inspection, etc. are written into the IC card. If necessary, the patient goes to an inspection room, in which he/she is inspected and the results of the inspection are written into the IC card as in the forego- 60 ing. Likewise, the patient further goes to pertinent sections and is given necessary treatments in succession, and information items are written into the IC card or the contents of the IC card are updated in correspondence with the treatments. Lastly, the patient receives 65 medicines prescribed on the basis of the information contained in the IC card, at a pharmacist's office. On that occasion, the fee is automatically paid from, for
example, the deposit account of the patient through a bank system externally connected.
With the prior-art example, however, notwithstanding that the patient must go to a large number of sections in succession within the hospital, no means is comprised for effectively mforming the patient of the guides of the goals, the instructions of precautions, etc., and such matters are often conveyed orally. This has led to such problems that many mistakes arise and that a wasteful time is expended for seeking the desired section.
SUMMARY OF THE INVENTION:
The present invention has been made in order to solve the aforementioned problems, and has for its object to provide a system for processing IC cards with a display function in which guidance information etc. to be reported to the user of each IC card are visually displayed on the IC card, thereby to effectively convey information to the user.
According to the present invention, the object is accomplished in such a way that a display element of liquid crystal or the like, and a power supply element (for example, lithium cell) for driving the display element are incorporated in the IC card, thereby to establish the function of displaying information written in a predetermined format, while the control unit of an IC card reader/writer is adapted to generate the guidance information etc. to be reported to the user, on the basis of information already stored in the IC card and other information obtained anew, thereby to establish the function of writing the display information into the IC card in the predetermined format.
The IC card in which the display element and the element for supplying power thereto are built has the function of displaying the information items internally stored, ordinarily some of the stored items, in the statuses which the user can directly see with the eye, such as letters, characters, numerals and patterns. The information displaying function can be demonstrated while continuing for a required period of time owing to the power supply element.
Accordingly, the IC card is inserted into the card reader/writer to execute predetermined information processing and simultaneously to write in predetermined forms the goal guides, precautions etc. which are to be displayed on the card. Thus, even after the IC card is taken out of the card reader/writer, the information can be conveyed for the required time in the state in which the user can directly see it with the eye.
