10-ti jan Nimewo ak 8-ti jan Nimewo Konvèsyon Relasyon nan Kat Kontwòl Aksè

Anjeneral nan sistèm kontwòl aksè a, nimewo kat 8-bit la se wiegand26-bit pwodiksyon, nimewo kat 10-bit la se wiegand34-bit pwodiksyon.
Pa egzanp, enprime sou yon kat:
0013961168 10-nimewo kat bit,
oswa
213 02000 3+5 8-nimewo kat bit.
10-nimewo kat bit 0013961168, konvèti an egzadesimal se 00 D5 07 D0.
8-nimewo kat bit 213 02000, premye a 3 chif 213 converted to hexadecimal is D5, the last five digits 02000 converted to hexadecimal is 07 D0.

Se poutèt sa, the rules can be found: First, the 10-digit conversion to hexadecimal is 4 bytes, 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.
