How to read the results
Serial number
This is the number read from the badge (UID or CSN), in decimal or hexadecimal. Type it as displayed by your reader or software: spaces and colons are ignored.
26 bits
The 24 least significant bits are split into a site code (1 byte) and a card number (2 bytes). The two parity bits at each end are added in the full frame.
32, 37 and 40 bits
The value is limited to the 32, 37 or 40 least significant bits. In 32-bit LSB, the four bytes are read in reverse order.
The calculation is done in your browser: no number is sent to a server. The results are an input aid. Always check them with a known badge before a roll-out.
