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.
