Na-emekarị ke ohere akara usoro, 8-bit nọmba kaadị bụ wiegand26-bit mmepụta, 10-bit nọmba kaadị bụ wiegand34-bit mmepụta.
Ọmụmaatụ, ibi akwụkwọ na a kaadị:
0013961168 10-bit nọmba kaadị,
ma ọ bụ
213 02000 3+5 8-bit nọmba kaadị.
10-bit nọmba kaadị 0013961168, tọghata hexadecimal bụ 00 D5 07 D0.
8-bit nọmba kaadị 213 02000, nke mbụ 3 digits 213 ghọrọ ka hexadecimal bụ D5, ise gara digits 02000 ghọrọ ka hexadecimal bụ 07 D0.

Ya mere, iwu pụrụ ịchọta: First, 10-ọbula akakabarede hexadecimal bụ 4 bytes, mbụ byte adịghị mkpa, nke abụọ byte na-ghọrọ ka mbụ 3 digits nke 8-bit nọmba kaadị, nke atọ na nke anọ nke bytes na-tọghatara ọnụ n'ime ikpeazụ 5 digits nke 8-bit nọmba kaadị.
Excel usoro =(MOD(X,256*256))+(MOD(Int(X /(256*256)),256)*100000).

Ọ nwere ike hụrụ si n'elu na 10-bit nọmba kaadị na ohere akara bịaranụ usoro nwere ike ghọọ 8-bit nọmba kaadị site na otu algọridim, na 8-bit nọmba kaadị siri ike weghachi ka a 10-bit nọmba kaadị.
