Description

[Detailed Description of the Invention] (a) Field of the Invention This invention relates to an automatic teller machine used in banking, for example, in which an IC card having both a magnetic stripe and an IC contact is used as a transaction medium. This I
The present invention relates to an IC card identification method in an IC card reader/writer that records and reproduces card information on a C card.

(B) Background of the Invention At present, there are multiple types of IC cards such as JPN, USA, and BULL cards, depending on the format of the IC contacts, the contact position, and the difference in frequency.

Therefore, in order to process (read) these plural types of cards with one IC card reader/writer, the following functions are adopted for the IC card reader/writer.

Before the user of the OIC card inserts the card, the user specifies the type of paper card using the input device.

The internal processing function of the OIC card reader/writer is structured to automatically change the read/write position and frequency of the IC connector for possible combinations, and automatically try reading/writing multiple times until normal reading/writing is achieved.

However, since the former method relies on manual operation by the user,
This has the disadvantage that it requires a lot of effort on the user's part and makes the operation complicated.

In addition, according to the latter method, it is necessary to try many times until the correct contact position and frequency are selected, resulting in a problem that the processing time becomes long.

(c) Purpose of the Invention In view of the above points, this invention provides an IC card with a magnetic stripe, and by recording a code for identifying the type of IC card in the magnetic stripe, the IC card reader/writer side can use the magnetic stripe. An object of the present invention is to provide an IC card identification method that can identify the type of IC card by first reading the stripe.

(d) Structure of the invention This invention provides an IC card with a magnetic stripe,
The present invention is characterized by an IC card identification method in which a code for specifying the type of IC card is provided in the magnetic stripe, and an IC card reader identifies the type of the 10 cards by reading this code.

(e) Effect of the invention According to this invention, a magnetic stripe is added to the IC card, and a code for identifying the type of IC card is recorded on the magnetic stripe, so that the IC card reader/writer side can detect the inserted IC card. By first reading the magnetic stripe, the type under the IC car can be identified, and the IC contact position and clock frequency can be automatically selected.

(F) Effects of the Invention Accordingly, the type of the inserted IC card can be instantly identified and the IC card reading/writing process can be started accordingly, so that the process can be performed in a short time without bothering the user.

(g) Examples of the invention An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A1 shows an IC card according to the present invention, and shows different types of cards AI and A2.

A code identifying the type of each IC card is also recorded in the magnetic stripe 2.4 of A2.

FIG. 2 shows an IC card reader/writer capable of handling the IC cards AI and A2 shown in FIG. 1, and is provided with a card transport system 6 that communicates with the card insertion slot 5. This card transport system 6 has pulleys 7a, 7b18a, 8b, respectively.
It is constructed by vertically disposing two belts 9.10 facing each other, and a card running surface 11 is formed between the re-conveying belts 9,10.

The motor M drives the lower conveyor belt 10 via the belt 12 and pulley 13.

A card running surface 11 is inserted in the middle of the card transport system 6.
A magnetic head 14 for recording and reproducing card information is placed at the bottom, and a presser roller 15 is placed at the top.

In addition, IC connectors 16.1 are provided on the outside of both ends of the card transport system 6.

Figure 3 shows the control circuit of an IC card reader/writer.
Reference numeral 18 includes a memory 19 and is connected in parallel 1020 to send and receive signals.

The magnetic head 14 is connected to the IC card A1. The card information is read from the magnetic stripe 2.4 of A2 and sent to the CPU via the amplifier 21, FM decoder 22, and serial/parallel converter 23.

Card detection signals from sensors S1 to S5 are sent to sensor circuit 2.

Depending on the type of IC card, the switching circuit 26 selects and switches the oscillators 08CI and 080228, and the signal is sent from the switching circuit 29 to the IC connectors 16 and 17. 30
is a serial-parallel converter, and 31 is a switch circuit.

The operation of the thus configured card reader/writer will be explained with reference to the flowchart of FIG.

In FIG. 4, when the inserted IC card is detected by the sensor S1, the card transport system 6 is driven by the motor M in the forward rotation direction at high speed to transport the card, and the IC card reaches the magnetic head placement position and the sensor S1 detects the inserted IC card. When S3 turns ON, card transport is stopped, and the magnetic head 14 reads the code in the magnetic stripe of the IC card to identify the type (steps n1 to n7).

Assuming that the IC card inserted according to the above identification is type A1 in Figure 1A, motor M is driven at low speed, and I
The C card A1 is transported to a position where the leading end in the card insertion direction (the same applies hereinafter) is detected by the sensor S5, that is, directly below the IC connector 16, and the motor M is stopped (step n8).

Then, the motor M rotates in reverse at high speed to transport the IC card A1 in the opposite direction, and returns it to the card insertion slot 5 to complete the process (steps n15, n16, n17, n1).

However, if the IC card identified in step n7 is type A2 shown in Figure 1, the motor M reverses at high speed to send the IC card A2 toward the card insertion slot 5, and the rear end of the card is detected by the sensor S2. Accordingly, the rotational force of the motor M is reduced and the motor M is stopped at the position where the sensor S1 detects the rear end of the card, that is, the position where the IC card A2 is directly above the IC connector 17 (steps n20 and n25).

Then, connect solenoid 5OL2 to ONL, IC connector 1

Then, the motor M reverses at high speed, returns the IC card A2 to the card insertion slot 5, and ends the process (step n17).

For the IC card inserted in this way, the type of the IC card is first identified by reading the code in the magnetic stripe 2.4 by the magnetic head 14, and the IC connector 16. ．． Because it is automatically transported to one of the 17 positions for reading and writing processing,
IC card reader/writer processing can be quickly automated.
