10-ໝາຍເລກບິດ ແລະ 8-bit ການປ່ຽນແປງຄວາມສຳພັນຂອງບັດຄວບຄຸມການເຂົ້າເຖິງ

ປົກກະຕິແລ້ວໃນລະບົບການຄວບຄຸມການເຂົ້າເຖິງ, ເລກບັດ 8-bit ແມ່ນຜົນຜະລິດ wiegand26-bit, ເລກບັດ 10-bit ແມ່ນຜົນຜະລິດ wiegand34-bit.
ຍົກ​ຕົວ​ຢ່າງ, ການພິມໃນບັດ:
0013961168 10-ເລກບັດ bit,
ຫຼື
213 02000 3+5 8-ເລກບັດ bit.
10-ເລກບັດ bit 0013961168, ປ່ຽນເປັນເລກຖານສິບຫົກແມ່ນ 00 D5 07 D0.
8-ເລກບັດ bit 213 02000, ທໍາອິດ 3 ຕົວເລກ 213 converted to hexadecimal is D5, the last five digits 02000 converted to hexadecimal is 07 D0.

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