Why does paper attendance fail?
- Faking: someone signs for an absent friend so a session is deducted or recorded for them.
- Loss: sheets are forgotten at the pitch, get wet or get damaged.
- No data: you cannot know each group's attendance rate without typing the paper in by hand.
- Delay: you learn a member dropped out after weeks, not in the first week.
- Lost training time: if roll call and signing take 5 minutes of a 60-minute session, more than 8% of every session is gone.
What are the alternatives to paper, and which work?
| Method | Notes |
|---|---|
| A spreadsheet the coach fills in | Better than paper, but it still depends on the coach typing and does not prove the member was there. |
| A printed static QR code | It can be photographed and sent to someone who did not come, so it cannot stop faking. |
| A personal rotating QR code | It changes every minute, so a screenshot is useless, and it proves the member is in front of the coach at scan time. |
How does rotating QR attendance work?
- The member opens their app and sees a personal code that refreshes every 60 seconds.
- The coach points their phone camera at the code and attendance is recorded in seconds.
- A session is deducted from the member's balance (if they are on a session pack), and the attendance shows in the dashboard.
And if there is no internet at the pitch?
This is the most common objection, and it has an answer. The coach scans the code offline, the attendance is stored encrypted on their phone, and it uploads automatically when the network is available. If a duplicate arrives for the same member in the same session, the first scan stands and the duplicate is flagged for review, so attendance is never counted twice.
Special cases and how to handle them
- A member forgot their phone or the app failed: the coach or front desk records them manually from the group list.
- A first-time visitor: record them as a visitor without creating a subscription.
- A substitute coach: give them only the attendance permission, without report or money permissions, and withdraw it when their cover ends.
- A duplicate scan: the first stands and the duplicate goes to management, so balances are unaffected.
A two-week rollout
- Prepare the data: groups, coaches and members. Your lists can be imported from Excel.
- Invite everyone: each member and coach joins with an invitation code and verifies their phone number.
- Train coaches for ten minutes: opening, scanning, and what to do if the internet drops.
- Run both for a week: record digitally and keep paper as a backup until you are comfortable.
- Stop the paper: after a week you confirm the numbers match.
A short note you can send coaches on day one: "From today we record attendance by scanning the code. Open the camera and point it at the code the player shows. If the attendance confirmation does not appear, tap manual entry. Do not drop the paper sheet this week."
How to read the attendance report
The most important number is the attendance rate: members who attended ÷ members registered in the group.
Common mistakes to avoid
- Not training the coaches: a short session is enough, but do not skip it.
- Ignoring the coach's battery: keep a spare charger at the pitch.
- Not following the numbers: the real benefit shows when you read the attendance report weekly.
How to measure whether the move worked
- The time a group takes to record attendance (the target: seconds, not minutes).
- The gaps between a member's balance and what the academy calculates disappear.
- You spot slipping members in the first week, not the first month.
