Yes, you can access Priority Pass lounges without a physical card by using the Digital Membership Card available through the Priority Pass mobile app. Once you have registered your account online or through the app, your digital card displays a QR code that lounge staff can scan upon entry. This is particularly useful for those who receive Priority Pass as a benefit through a credit card but haven't received their physical kit yet. However, it is vital to check if your specific membership type supports digital access, as a very small number of legacy or bank-issued accounts may still require the physical card. Additionally, some lounges may accept the eligible credit card itself (like certain Amex or Chase cards) as proof of membership, but the app is the most reliable method.
