2>.Work voltage:DC 5V
3>.Work current:40mA
4>.Read frequency:13.56MHz
5>.Communication Interface:UART(3pins)
6>.Read distance:about 5cm(For Mifare S50 S70,Desfire,FM1208 Card)
7>.Work Temperature:-20℃~85℃
8>.Work Humidity:0%~95%RH
9>.Size:39*18*3.7mm
 
Interface Description:
1>.VCC:Input for positive of work voltage.

Note:Module just have 3-cables.It just use TXD of UART.
 
UART Protocol Introduction:
1>.Protocol Header:0x02
2>.Data Length:0x09
3>.Card Type:0x01(More refer to card type)
4>.Card Data:SN0~SN3
5>.XOR Check:1 Byte.Result of other bytes check except protocol header
6>.Data end:0x03
 
Card type(Module can not read all card):
1>.0x02:EM4100((Support))
2>.0x01:Mifare 1K(Not support)
3>.0x03:Mifare 4K(Not support)
4>.0x10:HID card(Not support)
5>.0x11:T5567(Not support)
6>.0x20:ID card(Not support)
7>.0x21:ISO14443B(Not support)
8>.0x22:FELICA(Not support)
9>.0x30:15693 Tag(Not support)
10>.0x50:CPU card(Not support)
11>.0x51:Sector information(Not support)
12>.0xFF:Keyboard data(Not support)
 
Example:
If receiver data is 02 0A 02 2E 00 B6 D7 B5 F2 03.It is means:
1>.The first byte 0x02 is data start flag.
2>.The second byte 0x0A is total length of data.It include start and end byte.
3>.The third byte 0x02 is means the type of card is EM4100.
4>.The 4th to 8th bytes(0x2E 0x00 0xB6 0xD7 0xB5) is card number.The 4th byte 0x2E is a hidden card number.
5>.The 9th byte 0xF2 is XOR Check byte.
6>.The 10th byte is data end flag.
 
Application:
1>.Attendance
2>.Access control
3>.Industrial control
 
Note:
1>.It just need three wires.
2>.Module just can send data.
3>.User need write code according to UART Protocol Introduction as shown.
4>.Please stay away from interference sources.
