Generate unique bingo cards with verification QR
In short
BingoShow generates cards that follow the French 90-ball bingo format, with a unique verification QR per card. PDF ready in under 30 seconds.
Printing the cards is probably the most strategic step in your prep. A few minutes of care here saves hours of stress on the day.
1 What you need
- A session already created (90-ball variant by default).
- An A4 laser or inkjet printer — a home printer is fine.
- White 80 gsm paper (the standard photocopy weight). 100 gsm feels more pro.
- 2 minutes for generation, 10-20 minutes for printing depending on quantity.
2 Generate the PDF
Cards tab of your session → "Generate" button. Three choices to make:
1
How many cards
60, 120, 180, 300 or 600. Plan 15-20% more than the expected number of attendees.
2
The layout
1, 2, 4, 6 or 8 cards per A4 sheet. The more per sheet, the smaller they are.
3
Options
Verification QR, visible card number, association logo.
120
cards at 4/page = 30 pages
180
cards in sheets of 6 = covers 1-90
< 30 s
PDF generation time
Good to know: On some laser printers, disable the "Fit to page" option to keep the exact margins needed for the QR code.
3 Customise the cards
The right-hand panel of the editor lets you add your personal touch:
- Event title (e.g. "Year 6 field-trip loto").
- Association logo in the top-left.
- Main sponsor at the bottom of the card.
- Accent colour (borders, numbers).
- Simulated paper type (white, ivory, recycled).
Pro tip
Print 5 test cards before running the full 300. Check legibility, margins, and QR scanning on 1-2 cards. 30 seconds that save the day.
4 Check a winning card
The crucial moment of the game. Two methods, your choice:
📱 Scan the QR
- Open the BingoShow console
- "Verify a card" button
- Point the camera at the QR
- Result in 1 second
🔢 Type the number
- Read the 5-digit number at the top of the card
- Type it into the console
- Click "Verify"
- Instant result
5 Common mistakes
QR not read: turn up the screen brightness and check the margin around the QR is intact. If nothing works, type the number by hand.
PDF cut off when printing: untick "Fit to page" in the print dialog. Choose "Actual size" or "100%".
Did you know?
Every card carries an invisible cryptographic signature. It's impossible to forge a card that would "pass" verification. Security is total.
