Comparing between MIFARE 1 S50 card and ATMEL Temic 57 card

NXP Philips MIFARE 1 S50 card


The card type is MIFARE 1 S50 encrypted card. There are 16 sections in Mifare 1S50 card, our locks information will be put in one section only, and the rest 15 sections are opening to you to write different system information so that you can make the same card to do many other things, such as park the card, pay the bill etc. One section is only available for one system, but information of one system can be written into several sections, which is based on the capacity of the system program. This is so-called “all-in-one-card” or “one card solution”.
