10-bit Number Ary ny fifandraisana amin'ny fiovam-po isa 8-bit an'ny karatra fanaraha-maso

Matetika ao amin'ny rafitra fanaraha-maso ny fidirana, Ny laharana karatra 8-bit dia wiegand26-bit output, Ny laharana karatra 10-bit dia wiegand34-bit output.
Ohatra, fanontana amin'ny karatra:
0013961168 10-laharana karatra bit,
na
213 02000 3+5 8-laharana karatra bit.
10-laharana karatra bit 0013961168, miova ho hexadecimal dia 00 E5 07 D0.
8-laharana karatra bit 213 02000, ny voalohany 3 isa 213 converted to hexadecimal is D5, the last five digits 02000 converted to hexadecimal is 07 D0.

Ary noho izany, the rules can be found: First, the 10-digit conversion to hexadecimal is 4 oktety, the first byte does not need, the second byte is converted to the first 3 digits of the 8-bit card number, the third and fourth the bytes are converted together into the last 5 digits of the 8-bit card number.
Excel formula=(MOD(X,256*256))+(MOD(INT(X/(256*256)),256)*100000).

It can be seen from the above that the 10-bit card number in the access control attendance system can be converted into an 8-bit card number by an algorithm, and the 8-bit card number is difficult to restore to a 10-bit card number.
Most of the access control attendance systems developed and produced by Seabreeze Smart Card Co.,Ltd are compatible with wiegand26 and wiegand34, and the software can also freely choose 8-bit card number or 10-bit card number operation.
