When selecting smart cards, many customers always ask about the differences among IChe financial standard.

How to distinguish ID card, IC card and CPU card from their appearance? IC, ID and CPU cards are one of the commonly used smart cards. It is difficult to distinguish their differences from the appearance. Here are some tips for you to tell.

How to distinguish IC, ID and CPU chips from white cards? Generally, the ID white card will have an 18 digit internal code number on its surface. The internal code number is arranged as follows: the first 10 digits of the card number+space+3 digits+comma+5 digits. Both IC and CPU chips can be made into white cards and color cards. Both IC white cards and CPU white cards are white on the front and back. Without card numbers, they cannot be distinguished from each other in appearance; The same is true of color printing cards, which are indistinguishable in appearance.

If IC, ID and CPU chips are made into keychain access cards, how can they be distinguished? Generally, the ID keychain card surface will be engraved with a 10 digit internal code number, while the IC keychain and CPU keychain can not be distinguished from each other from the appearance, so they can be made into solid color keychain or color printed keychain. Only from the internal coil, you can use a flashlight to see the coil inside the card from the back of the card in the dark: generally, the ID card coil is round, and the coil turns are relatively large; The IC card coil is elliptical, with less turns; The CPU card has many small coils.

All the above discrimination methods for ID card, IC card and CPU card are generally described. However, since these cards can be customized according to requirements, some special cases are not excluded, and it is recommended to use professional equipment for testing.

In order to more accurately judge and distinguish the chip model of the card, the way of [sensitive words] is to test the read/write card through ID card reader, IC card reader and CPU card reader. The high-frequency IC card can also be read and tested through the NFC tool of the mobile phone, or directly contact our card manufacturer to test with professional equipment. The safety level of CPU is high. If you need to make a card if only the sample card does not know the chip model, you will not be able to read and make it. 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 to send samples for testing.
