When the smart card in the selection, there are always many customers ask the difference between IC, ID, CPU chip card, choose the chip is different, the price will deviate, then in the actual application of smart card to how to select it? We first look at the definition of each of the ic card, id card, cpu card.

IC card is called integrated circuit card, also known as smart card. Can read and write, large capacity, encryption function, reliable data records, more convenient to use, such as a card system, consumer systems, etc., at present, the main PHILIPS Mifare series cards and domestic IC chip cards.

ID card, also known as identification card, is a non-writable induction card, containing a fixed number, mainly Taiwan's SYRIS EM format, the United States HID, TI, MOTOROLA and other types of ID cards.

CPU card is also called smart card, the integrated circuit inside the card includes processor CPU, programmable read-only memory EEPROM, random memory RAM, solidified card operating system COS (Chip Operating System) and read-only memory ROM, etc.. The card is equivalent to a microcomputer without a monitor 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.

There are microprocessor and IC card operating system (COS) in the CPU card. When the CPU card is operated, encryption and decryption algorithms can be carried out (algorithm and password are not easy to crack), and mutual password authentication between the user card and the system is required several times (and extremely fast), which improves the security performance of the system and has a good effect on preventing the generation of counterfeit cards.

It can be seen that ic card is encryptable memory card, id card is read-only low-frequency card, CPU card is the upgrade product of IC and ID card, which is a chip card with security performance reaching the financial standard.

If IC, ID, CPU chip made into white card how to distinguish? General id white card surface will have 18-bit internal code number, internal code number arrangement rules for the front 10 card number + space + 3 digits + comma + 5 digits. ic, cpu chip can be made into a white card and color card, ic white card and cpu card white card front and back are white, no card number, from the appearance alone is not distinguishable; color printing card is the same, from the appearance is not distinguishable.

If the IC, ID, CPU chip made into a key fob access card how to distinguish? General ID Keyfob card surface will be engraved with 10-bit internal code number, and IC keyfob and CPU keyfob can not be distinguished from the appearance, can be made of solid color keyfob or color printing keyfob, only from the internal coil, can be seen in the dark with a flashlight from the back of the card to see the internal coil of the card: general ID card coil is round, and the number of turns of the coil is more; IC card coil is oval, the number of turns is more Less; CPU card with small coils with more.

All of the above about ID card, IC card, CPU card to distinguish the way are conventional, but because these cards can be customized according to the requirements, so do not exclude some special circumstances, it is recommended to use professional equipment to test.

In order to more accurate judgment to distinguish the card chip model, the best way is through the ID card reader, IC card reader, CPU card reader to read and write card test, high-frequency IC card can also be through the cell phone NFC tool chip model reading test, or directly contact our card manufacturers, with professional equipment for testing. Only if you know the system communication protocol or the detailed chip model, you can let the manufacturer select the CPU chip card that meets the communication protocol and send the sample for testing.
