We offer our PHS in different specification variations in order to guarantee a safe and error-free production for every use in the field of PIN processing. In principle, the system can always be used when confidential information should be protected from unauthorised access. These use cases usually occur within postal PIN mailings, but there are also other applications where character strings are concealed with PIN labels which leave visible traces if tempered with. Flawless assignment of a PIN to its receiver or the accompanying card, completely database supported processes, and the automatic deletion of information from the database after processing, are only some features which distinguish our PIN processing system and make it especially secure.
