How to use the Membership Card QR Generator
One card per member
Give every member their own card with their own member number. The QR code carries the number, tier, and expiry, and your check-in system matches it against the member record. Never issue two members the same number, and never print a card without an expiry: a card with no end date is a card you can never retire. When a member renews, issue a fresh code with the new expiry rather than editing the old one.
Tier means something, or it means nothing
A tier on the card is a promise. If Gold members get guest passes or off-peak access, staff must be able to see that from the scan and honour it the same way every time. Decide the benefits per tier before printing, write them down where staff can find them, and keep the tier in your member system as the source of truth. The card shows the tier; the system decides what it unlocks.
Checking cards at the door
Test the full check-in flow with a sample card: scan it, confirm the member record opens, and confirm an expired card is refused. Print the member name and number in plain text beside the code so staff can verify a card even when the scanner is busy. Keep the quiet zone around the code and print dark modules on a light background with strong contrast, and test under the actual lighting at your entrance.
