The Italian Alpine Club's (CAI) Pass app allows you to scan the QR code found in MyCAI and on the membership certificate of each Italian Alpine Club member to verify their membership validity.
The CAI Pass app can be used by entities that provide services reserved for Italian Alpine Club members or that offer discounts to them, to verify entitlement to such services and discounts. Specifically, the app allows you to read the QR code found on both the membership card and the membership certificate and graphically displays the authenticity and validity of the membership to the verifier, including the name and surname of the cardholder or certificate holder, the section to which they belong, and the membership category.
No internet connection is required to use it, so it can be used even in refuges without internet access.
