Product Description
M1 Card
1) Major specifications
Capacity is 8K-bit EEPROM
Divided into 16 sectors. Each sector is divided into 4 blocks while each block includes 16 bytes. Information is accessed by block
Each sector has independent group of ciphers and access control
Each card has unique sequential number of 32 bits
Supports multi-card operation with anticollision scheme
No power source, self-contained antenna, ciphered control logic and communication logic circuit
10 years of data duration, 100, 000 recordable times and limitless reading times
Operation temperature: -20 degrees~50 degrees (humidity is 90%)
Operation frequency: 13.56MHz
Communication rat e: 106KBPS
Reading / writing distance: Within 10mm (relevant to the reader / writer)
2) Operation principle
The electrical part of card is composed of antenna and ASIC.
Antenna: Coil made of several wires, which is suitable to be assembled to ISO card.
ASIC: Composed of high-speed (106KB baud rate) RF interface, control unit and 8K-bit EEPROM.
Operation principle: Under the prompting of a group of electromagnetic wave with fixed frequency emitted from reader / writer, the LC serial resonance circuit, with the same frequency as that emitted from the reader / writer, in M1 card will cause resonance that in turn will produce charges in capacity. An electronic pump with unilateral passage at the other end of the capacity will transfer the charges to another capacity for storage. When the charges are accumulated to 2V, the capacity can be used as a power source to provide operation voltage for other circuits to emit the tag data or receive data from reader / writer.
3) Communication from M1 RF card and reader / writer
Answer to request
The communication protocol and baud rate of M1 RF card have been defined in the manufacturer. When any card is within the operation range, reader / writer will communicate with it in specific protocol and then confirm whether this card is M1 RF card, I. E. Verify its card model.
Anti-collision Loop
When various cards are within the operation range, reader / writer will select one card from them to operate with anti-collision loop while other cards will be in spare mode to wait for next selection. This process will return the sequential number of selected card.
Select Tag
Select the sequential number of selected card and return the capacity code of card.
3 Pass Authentications
After selection of card to be processed, reader / writer will confirm the sector number to be accessed and then verify its cipher. Upon 3 pass authentications, they can communicate with each other by means of ciphered stream. (Before selection of another sector, its cipher must be verified. )
Operations on data block
Read: Read a block;
Write: Write a block;
Increment: Increase value of data block;
Decrement: Decrease value of data block;
Restore: Store the content of block into data register;
Transfer: Write the content of data register to a block;
Halt: Put card in pause state.
