10-bit Number Mo e 8-bit Number Relationship of the Access Control Card

ʻOku faʻa ʻi he founga puleʻi, Ko e fika ʻo e kaati ʻe 8 ko e wiegand26-kiʻi Output, Ko e fika ʻo e kaati ʻe 10 ko e wiegand34-kiʻi Output.
Hange ko ʻeni, paaki ʻi ha kaati:
0013961168 10-fika ʻo e kaati uʻi,
pe
213 02000 3+5 8-fika ʻo e kaati uʻi.
10-fika ʻo e kaati uʻi 0013961168, papi ului ki he wilder ko e 00 D5 07 D0.
8-fika ʻo e kaati uʻi 213 02000, ʻa e ʻuluaki 3 Mataʻifika 213 converted to hexadecimal is D5, the last five digits 02000 converted to hexadecimal is 07 D0.

Ko ia, 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.
