QR code check-in: how to scan members and guests at the door
A queue at the door, a volunteer squinting at laminated cards, a few people who “forgot” theirs: QR code check-in solves all three. Here is how it works and how to set it up with nothing more than a phone.
- Each member card or ticket carries its own QR code.
- Any smartphone can be the scanner, and several volunteers can scan at once.
- The scanner says in one second: valid, expired, unknown or already used.
- You know how many people came, without counting by hand.
How QR code check-in works
Each member card or ticket contains a unique QR code. At the door, a volunteer points a phone at it. The scanner looks the code up and shows the result immediately, usually with a colour: green for valid, red for expired, already used or unknown. The member keeps walking; the volunteer moves to the next person.
What you need
- Cards or tickets with one QR code per person.
- One or more smartphones with the scanner open.
- A network connection at the door, or a fallback for weak signal.
- One volunteer per entrance, two at peak times.
No special scanner or turnstile is needed. A phone camera reads QR codes in well under a second, even from a phone screen at full brightness.
Where clubs use it
- Entrance to the clubhouse, gym or pool.
- Home matches with free entry for members.
- Parties, galas and dinners with tickets.
- General meetings, to record who attended and could vote.
- Training camps and trips, to check everyone is on the bus.

Handling the tricky cases
Expired membership: the scanner shows it clearly. Decide in advance what the volunteer does: let them in and remind them to renew, or send them to the desk.
Screenshots and copies: a ticket can only be scanned once, so a shared screenshot is refused the second time. For member cards, the name shown on the scanner lets the volunteer check it is the right person.
Weak network: Wallet cards display offline, so members can always show their code. Keep a printed list of members as a backup in a basement or a field without signal.
Member without a smartphone: print the QR code of their card on paper. It scans exactly like the phone version.
Setting it up with MPass
Every MPass membership card and ticket goes into Apple Wallet or Google Wallet with its own QR code. Any phone in your team can open the scanner. It shows the member’s name and tier, rejects expired cards and duplicate tickets, and counts entries as they come in.

Frequently asked questions
Do I need a special device to scan QR codes?
No. A smartphone is enough. Several volunteers can scan with their own phones at the same time.
Does QR code check-in work without internet?
Members can always display their Wallet card offline. The scanner needs a connection to check the code live; keep a printed list as a backup where the signal is weak.
Can a QR code ticket be used twice?
No. Once a ticket has been scanned, the scanner refuses it if it is shown again.
