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.

Barcode Technology And RFID Technology Similarities And Differences

Barcode technology and RFID technology are two common technology in our life. Barcodes and RFID are everywhere you go. Now let me show you the similarities and differences between them. One dimensional barcode and two dimensional barcode Barcodes are graphical representations of information that can be made into barcodes and then fed into a computer using the appropriate scanning device. Currently, one-dimensional barcode and two-dimensional barcode are common. One dimensional barcode only expresses relevant information in one direction, but does not express any information in the vertical direction. One dimensional barcode is characterized by fast information input and low error rate. However, the data capacity of one-dimensional barcode is small, and the barcode cannot be read after it is damaged. Two-dimensional barcodes store information in horizontal and vertical two-dimensional space. They record information by distributing black and white graphics on the plan...

Why Do Some People Like To Collect Custom PVC Badges

Custom PVC badges are like stamps.Each unique label may represent an era or a culture.Custom PVC badges are charming. Last year, there was an exhibition in New York's Washington square called "Images As Virus", which was an exhibition of customized PVC badges of punk. This exhibition featured work by artists such As Barney Bubbles, Jamie Reid, Peter Fischli, Peter Saville, Malcolm Garrett and Linder Sterling.There are also The Buzzcocks, Ramones, Crass, Suicide, Joy Division, The Clash, The Sex Pistols, The Modern Lovers, Industrial Wombats, FAST Product, The Raincoats, Motorhead and other bands with rare   original peripheral badges. "I didn't have any money to buy the records I wanted.One day I happened to see a Scars' Adult - ery/Horror Show 'single badge, as long as one yuan, from now on I fell in love with badges "Kevin Pedersen said. Punk badge collectors don't buy a bunch of mass-produced knockoffs.Printing, toning, batch ...
