10-Helu bit a me ka pilina hoʻololi helu 8-bit o ke Kāleka Mana Mana

ʻO ka mea maʻamau i ka ʻōnaehana mana komo, ʻO ka helu kāleka 8-bit he wiegand26-bit output, ʻO ka helu kāleka 10-bit he wiegand34-bit output.
ʻo kahi laʻana, paʻi ʻana ma ke kāleka:
0013961168 10-helu kāleka bit,
a i ʻole
213 02000 3+5 8-helu kāleka bit.
10-helu kāleka bit 0013961168, hoohuli i ka hexadecimal is 00 D5 07 D0.
8-helu kāleka bit 213 02000, ka mua 3 huahelu 213 converted to hexadecimal is D5, the last five digits 02000 converted to hexadecimal is 07 D0.

Hiki i ka mea hoʻohana ke hoʻohana i kahi mea heluhelu / kākau kūikawā, 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.
