Smart cards, IC cards, ID cards and magnetic cards are our common cards. Although some customers know the field they use, they dont know the principle of its use and some customers dont know anything. In this case, let Card Cube Smart Card Company explain to us the principle of smart card IC card, ID using card and magnetic card.
Analysis of smart card, IC card, ID card, magnetic card use principle
IC card / ID card
Smart card also known as IC is a readable and writable chip card. Depending on the storage capacity, there are different chip types. Philips is now the most used chip type S50, Philips S70, Fudan FM1108, AT24C64,AT24C With the development of the market, 04 and other common chips, IC gradually replace the traditional membership card, magnetic cards and barcode cards. IC cards are widely used because IC cards and ID and barcode cards compared to the card, magnetic cards, barcode cards more secure, IC card chip has Password module, you can write the password inside, the password verification can read the card information, greatly improving the security of the card.
Magnetic stripe card
ID card is a read-only chip card, the information in the chip is the serial number written in advance, is the only serial number in the world, only read the unmodifiable serial number, so the use of ID card in the software, in fact, just try ID identification card in the number.

The main difference is the use of different behavior, ID card is induction read information, magnetic stripe card is swiped to read information, ID card is a chip, not easy to damage, magnetic stripe card easy to demagnetization.
Magnetic stripe card and barcode card trial principle is basically the same, is through the card number to read information, related membership information is also stored in the local computer or server, the difference is that the magnetic stripe card is the magnetic stripe to store the card number, barcode is printed on the card through the card printer, and then through the scan gun recognition. Magnetic and barcode cards are the least secure and a new magnetic stripe card can be copied at any time. The only advantage is the low cost.
