Each Mifare 1k has unique number (UID number). But you will find different UID number read by differen readers because the UID number of MIFARE 1K card has multiple
international standard encoding rules. Some NIC card numbers read by the card reader will be repeated, mostly because the card is not read according to the international coding
For example, the data of the 0th block of the 0th sector:
Manchester code (hex):
HEX big endian
1. The positive code is “2A83155E”, which is the first 4 bytes of 0 sector 0 block, a total of 8 numbers or letters.
HEX small endian
2, the inverse code is “5E15832A”, that is, the first 4 bytes of the 0 sector 0 block are reversed, a total of 8 numbers or letters.
ABA code (decimal):
1. The positive code is the decimal number converted by the Manchester code. According to the example, the result is “0713233758”, a total of 10 digits.
2. The inverse code is the decimal number converted by the Manchester code. According to the example, the result is “578468138”, a total of 10 digits.
