Anker Plessey Code

Anker Plessey Code is a continuous, variable length symbology used to encode hexadecimal data, maintained by the ADS Company. It was primarily used in retail environments prior to the development of EAN. Anker Plessey varies from the UK Plessey Code only in how the CRC is calculated.

ClosedThe Character Set

This symbology is capable of encoding all hexadecimal digits, 0-9 and A-F.

ClosedThe Symbology Structure

Each digit in an Anker Plessey Code symbol is encoded in 4 bars (or bits). Each wide bar followed by a narrow space represents a "1" bit; conversely, a "0" bit is encoded as a narrow bar followed by a wide space.

Each symbol appends two mandatory check digits to the end of the data.
