Encryption allows very long numbers to be encoded into relatively small barcodes. Typically, all barcodes (pass and access) are encrypted. In order to be able to scan encrypted barcodes in Sales, the setting EncryptedPassNumbers=TRUE must be included within the [Preferences] section of the Sales32c.INI file.

Only barcodes are encrypted; magswipes are never encrypted. For more information on the commands to use to encode barcodes, see the Salesware Layouts document.
