What’s the difference CPU card,IC card,ID card?


Their definition

As for the difference CPU card, IC card,ID card, let’s understand their definition first.
In a broad sense, IC=integrated circuit= integrated circuit card
Want card to have integrated circuit only (chip), can calculate IC card actually. ID card also calculates.
However, we often hope that the chip in the card cannot only record an ID number, we also hope that the chip can store information, do some encryption and decryption calculation or even logical operation.
At this point, we can narrowly define the former is an ID card, the latter is an IC card. Among them only hardware encryption and decryption ability, we call it the logical encryption card, have the logical operation ability, we call it the CPU card.

That definition out of the way, let’s move on to the physical structure

In addition to the substrate and chip, the main is the antenna. According to the interface points, cards can be divided into three types, here we assume that is a single chip card
  1. Contact type (no antenna)
  2. Non-contact (with antenna)
  3. Compound type (with antenna)

Summarize the difference CPU card, IC card,ID card from two aspects

Antenna: ID card work at the frequency of 125KHz, and the inductance value of the antenna is about hundreds of micro-hz. In terms of structure, there are many coils in the antenna, usually dozens of coils. IC card and CPU card antenna are the same, are working at 13.56MHz, the antenna inductance value is a few micro Henry, generally 2-8 coils.
Chip: ID card is basically just a memory, the chip is the simplest. IC card chip is the circuit that much encrypted attestation. The CPU card is the same as a small system, including a COS system.

The Preferred Material For Badge Making

Soft epoxy badges, soft epoxy key   chains and other badges are made of PVC material. PVC material   have always been the material of choice for badge manufacturers to make soft  epoxy products, which is inseparable from the related characteristics of PVC. PVC material is polyvinyl chloride, which is one of the largest plastic products in the world. Due to the rich synthetic raw materials of PVC resin, the demand for low price is increasing rapidly, and its status is gradually strengthened. The polyvinyl chloride resin is a white or light yellow powder and cannot be used alone and must be modified. PVC is a white powder with an amorphous structure, which has a small degree of branching and poor stability to light and heat. Different additives can be added according to different purposes, and polyvinyl chloride plastic can exhibit different physical properties and mechanical properties. A variety of hard, soft and transparent articles can be made by adding an appropri...

What Can UV Print?

"UV" means ultraviolet light.It is basically a form of piezoelectric ink-jet printing.The idea is that the UV waves emitted by the LED light react with the curing photosensitive agent in the UV ink, causing the pigment molecules in UV ink to solidify  the material surface, thus completing the printing action. UV printing is not limited by any material, can be in glass, plate, crystal, PVC, acrylic, metal, plastic, stone, leather and other surface color photo printing.It prints in one go without any plate making.UV plate printing color is beautiful and rich, wear resistance. UV protection, simple and convenient operation, printing image speed, in line with industrial printing standards, so also has a wide range of applications. Summarize The advantages Of UV Printing Wide application range, can be applied to many materials. Environmental protection.On the one hand noise pollution is relatively low, on the other hand unlike silk-screen printing with ...

What should I do if my card is not recycled?

You can cut out the card if the bank doesn't recycle it. But remember a few key points: Confirm with the bank and cancel the card completely. The back magnetic strip should be cut completely: cut completely from left to right. A single cut in the middle is useless. Personal information can still be read. Personal signature, cardholder's name part to be painted or cut out separately, throw away. The card number part had better also cut open. If it is PBOC 2.0 IC card (with both magnetic strip and contact IC card), it needs to destroy IC chip at the same time As for the following schemes: Burn off card: the PVC material of magnetic card adds flame retardant commonly, so combustion has certain problem. Strong magnet degaussing: at present, there is a widely used magnetic card technology, called "strong anti-magnetic". It has certain protective ability to magnetic field, so it is not safe. If you find my article very helpful and interested in me, you may...
