How to estimate it
Fermi’s official “Napkin math”
Visa is the biggest card company, so start with its cardholders. Call it 200 million people. How often does each one use a card in a day? Maybe 5 times, which makes about a billion a day.
- People with a Visa
- ≈ 200,000,000
- Uses each a day
- × 5
- Uses a day
- ≈ 1,000,000,000
- 1B ÷ 86,400 seconds a day
- ≈ 11,500
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Payments transactions
- 339.5 billion
- Cash transactions
- + 15.6 billion
- Total, fiscal 2026
- 355.1 billion
- ÷ 31,536,000 seconds a year
- ≈ 11,300
