Wireless transmission M1 card manufacturers Which is good / induction M1 card manufacturer M 1 card key indicators: capacity of 8K-bit EEPROM into 16 sectors, each sector for four, each 16 bytes in blocks access unit for each sector has a separate set of passwords and access control Each card has a unique serial number for 32 antenna, includes encryption control logic and communication with anti-collision mechanism supports multiple card operation without power, comes logic data retention period of 10 years, can be rewritten 100,000 times, read unlimited Operating temperature: -20 ℃ ~ 50 ℃ (temperature of 90%) Operating frequency: 13.56MHZ communication rate: 106KBPS reading distance: 10mm or less (with reader related) Applications: widely used in the field of urban radio frequency identification card, bus, subway, light rail, attendance and access control systems, business card systems, intelligent transportation, membership management, retail, insurance, medical, health care, schools and so on. 1.M1 use chip Philips Mifare 1 S50, Fudan FM11RF08 etc. (do labels, white card, printed card, Epoxy card, non-standard card, composite cards) 2. Chip Features: chip features: high reliability, easy operation, fast, anti-collision, can be adapted to a good variety of applications, encryption performance. 3. Card Technology: The surface offset printing process, the surface using scratch, abrasion process (UV oil / film), full-color beautiful patterns and text, increasing the card art, and production of precision, comprehensively improve the card value. Can be hot, hot silver handle, can be printed signature pieces, to play convex code, laser code, internal code and the number of water spray, can produce different surface visual effects according to customer requirements. 1, M1 card is divided into 16 sectors, each sector is composed of four (block 0, block 1, block 2, block 3) composition, (we will 16 sectors of 64 blocks by absolute address NO. 0 to 63, the storage structure as shown below: 2, the first sector of the block 0 0 (that is, absolute address 0), which is used to store the manufacturer code, has been cured, can not be changed 3, each sector of the block 0, block 1, block 2 data blocks can be used to store data.
