Smart card selection strategy | Analysis of the difference between IC card, ID card and CPU card

Time:2022-06-07 15:02:09


When selecting smart cards, many customers will always ask about the difference between IC, ID and CPU chip cards. Different chips will cause price deviations. So how to choose smart cards in practical applications? Come and learn with the smart card manufacturer! Let's first look at the respective definitions of ic card, id card and cpu card:

The full name of IC card is integrated circuit card, also known as smart card. It is readable and writable, has large capacity, has encryption function, reliable data recording, and is more convenient to use, such as one-card system, consumer system, etc. At present, there are mainly PHILIPS MIFARE series cards and domestic IC chips. Card;

The full name of the ID card is an identification card, which is a non-writable induction card with a fixed number, mainly in the EM format of Taiwan SYRIS, the United States HID, TI, MOTOROLA and other types of ID cards.

The CPU card is also called a smart card. The integrated circuit in the card includes a processor CPU, a programmable read-only memory EEPROM, a random access memory RAM, a solidified in-card operating system COS (Chip Operating System), and a read-only memory ROM. The card is equivalent to a microcomputer without display and keyboard. The data in the card is divided into two parts: external reading and internal processing to ensure the safety and reliability of the data in the card.

It can be seen from this that the ic card is an encrypted memory card, the id card is a read-only low-frequency card, and the CPU card is an upgraded product of IC and ID cards, and is a chip card whose security performance has reached financial standards.

How to distinguish id card, ic card, CPU card from the appearance? IC, ID, and CPU cards are all commonly used smart cards. It is difficult to tell the difference between them from the appearance. Here, I will share some tips for you to identify them.

If IC, ID and CPU chips are made into white cards, how to distinguish them? Generally, there will be an 18-digit internal code number on the surface of the id white card. The internal code number arrangement rule is the first 10 digits of card number + space + 3 digits + comma + 5 digits. Both IC and CPU chips can be made into white cards and color cards. Both the front and back of the IC white card and the CPU card white card are white, and there is no card number, which cannot be distinguished from the appearance alone; the same is true for the color printed card, which is indistinguishable.

If IC, ID and CPU chips are made into keychain access cards, how to distinguish them? Generally, the surface of the ID keychain card will be engraved with a 10-digit internal UID code number, while the IC keychain and the CPU keychain cannot be distinguished from the outside. Use a flashlight to see through the light from the back of the card to see the coil inside the card: generally, the ID card coil is circular, and the number of coil turns is relatively large; the IC card coil is oval, and the number of turns is relatively small; the CPU card has a small coil.

All of the above discrimination methods for ID cards, IC cards and CPU cards are based on normal circumstances, but because these cards can be customized according to requirements, some special cases are not excluded. It is recommended to use professional equipment for testing.

In order to more accurately judge and distinguish the chip type of the card, the best way is to read and write the card through the ID card reader, IC card reader, CPU card reader, and high-frequency IC cards can also be tested by mobile phone NFC. tool to read the chip model, or contact our card manufacturer directly to test with professional equipment. Because of its high security level, the CPU card cannot be read and made if only the sample card does not know the chip model. Select the CPU chip card that conforms to the communication protocol to send samples for testing.
