The UK Cards Association is the leading trade association for the cards industry in the UK and has issued two Standards relating the production of PIN mailers, which can be obtained from the UK Payment Standards unit:
- UK Cards Association Standard 71 (Bank Card PIN Mailer Security)
- UK Cards Association Standard 72 (PIN Mailer Evaluation Testing)
PIN mailers are used for the delivery by mail of Personal Identification Numbers to cardholders. The aim of the UK Cards Association accreditation scheme is to increase PIN Mailer security.
