10-Piekļuves kontroles kartes bitu numura un 8 bitu skaitļu pārveidošanas attiecības

Parasti piekļuves kontroles sistēmā, 8 bitu kartes numurs ir wiegand26 bitu izvade, 10 bitu kartes numurs ir wiegand34 bitu izvade.
Piemēram, drukāšana uz kartes:
0013961168 10-bitu kartes numurs,
vai
213 02000 3+5 8-bitu kartes numurs.
10-bitu kartes numurs 0013961168, konvertēt uz heksadecimālu ir 00 D5 07 D0.
8-bitu kartes numurs 213 02000, pirmais 3 cipariem 213 converted to hexadecimal is D5, the last five digits 02000 converted to hexadecimal is 07 D0.

Tāpēc, the rules can be found: First, the 10-digit conversion to hexadecimal is 4 baiti, 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.
