The present invention relates to a data recording medium having a shape.

[0002]

2. Description of the Related Art Heretofore, there has been known a business card size information card in which information such as voice / music is recorded by an optical reader for a compact disk. In this rectangular information card, a through hole having the same size (15 mm in diameter) as the center hole of the compact disc is formed in the center of the card, and information is recorded in a spiral line at the center of the through hole. .

FIG. 12 schematically shows a cross-sectional view of a conventional information card. This kind of card 10 has a transparent substrate 11, an aluminum film 12

At one end of the card 1, there is provided a second data recording section 6 for electrically storing second data which can be read or written by an external non-contact data reading / writing device. The second data recording unit 6 includes a one-chip nonvolatile semiconductor memory 5 for electrically storing the second data, for example, a flash memory or a magnetic bubble memory, and an external non-contact data read / write. A loop antenna (not shown) for communicating with the embedded device via magnetic flux or electromagnetic waves (radio waves) is provided. Further, the second data recording section 6 is provided with a control circuit for controlling the movement of data between the loop antenna and the nonvolatile semiconductor memory 5. The second data recording unit 6 records related information indicating or explaining the content of information recorded in the first data recording unit 2. This makes it possible to know in a non-contact state what information data is recorded in the first data recording section without actually putting the card on the optical reading device. The data stored in the second data recording unit 6 is mainly code data such as characters and symbols.

The nonvolatile semiconductor memory 5, the loop antenna and the control circuit constituting the second data recording section 6 are formed by a hybrid IC manufacturing printing technique. This loop antenna is formed by printing a conductive material having a predetermined impedance in a rectangular or circular shape with a predetermined impedance.

Then, by correcting the directivity and enlarging the reading area, data can be read in a non-contact manner without making the data reading device and the IC chip parallel.

Thus, the non-contact memory of "S label" can read data recorded on the IC chip even in bags or cardboards that cannot be read with a barcode. Therefore, only by passing the product on which the non-contact memory is pasted through the gate, it is possible to receive the microwave emitted from the IC chip and determine the type of the product. Since the amount of information that can be recorded on an IC chip is about ten times that of a barcode, various information can be included and the accuracy of product management can be improved.

The non-contact memory of "S label" has a storage capacity (user use capacity) of 918 bits and a reading distance of 3 bits.
The distance is 5 to 150 cm, and the writing distance is 5 cm. And 1
The processing speed per word (16 bits) is 1 reading.
0 ms, writing is 50 ms. That is, since there is an ability to identify 50 cards in 1.5 seconds, a plurality of pieces of information can be read at a time. The unique ID of the memory is 32 bits. Therefore, it is possible to perform the batch inspection of the products and the calculation of the charge at the cash register in an instant without making the customer wait, which is efficient.

In the card-shaped data recording medium according to the present invention, the non-volatile semiconductor memory element 5 provided in the second data recording section 6 is not affected by radio wave interference due to the magnetism of the optical disk on the back side of the card 1.

It is performed by a small scanner using a frequency of 2.45 GHz. This device is publicly known and its description is omitted.

The semiconductor memory 5 in the embodiment is an anti-fuse memory, that is, a non-reversible memory. For this reason, unauthorized data falsification is prevented.

In the embodiment, the attributes of data and information optically recorded on the card 1 are input to the memory 5 in advance. Then, the I of the card 1 is contacted wirelessly without contact.
After identifying the D code or the like as electronic data, the contents of data and information recorded on the card 1 can be confirmed.
