PASS (the Proof of Age Standards Scheme) is a government-backed scheme in the United Kingdom that gives citizens a valid and accepted form of proof-of-age identification. The scheme is supported by the Home Office, the Chartered Trading Standards Institute (CTSI) and the National Police Chiefs' Council (NPCC). It acts as an umbrella system: it does not itself issue identification cards, but various proof of age card schemes operate under the PASS umbrella, and issue cards which bear a PASS hologram as proof of authenticity and validity.
