The verdict in three sentences
A MoMo QR code at the till takes payment in 8 to 15 seconds versus 40 seconds in cash, with no change to hand back. Till errors fall ~80 % and the printed sign costs almost nothing. The real hurdle isn't technology but reconciliation discipline: every payment must be verified before releasing the customer.
Static or dynamic QR: which to choose
A static QR is a sign printed once; the customer types the amount. A dynamic QR generates a pre-filled amount from a terminal or the merchant app, removing customer entry errors.
| Criterion | Static QR | Dynamic QR |
|---|---|---|
| Setup cost | ~0 FCFA (printing) | Dedicated terminal/app |
| Amount | Typed by customer | Auto pre-filled |
| Entry-error risk | Medium | Near zero |
| Checkout time | 12-15 s | 8-10 s |
| Best for | Small shop, market | Queues, high volume |
| Bookkeeping match | Manual | Semi-automatic |
Checkout: QR mobile money vs cash
2026 figures (order of magnitude, Dakar and Kampala) show a clear gap on speed and reliability.
| Indicator | Cash | Wave QR (Dakar) | MTN MoMo QR (Kampala) |
|---|---|---|---|
| Time per transaction | ~40 s | 8-15 s | 10-15 s |
| Merchant fee | 0 % | 0-1 % | 0.5-1.5 % |
| Change-making | Required | None | None |
| Till error rate | Baseline | -80 % | -75 % |
| Urban customer adoption | — | 60-75 % | 55-70 % |
| Traceability | Low | High | High |
Mini case study
Awa runs a ready-to-wear shop in Kampala with 90 transactions a day. In cash, each takes ~40 s; with the MoMo QR, ~12 s. She saves about 42 minutes of queue per day, roughly 21 hours a month. On an average basket of 8,500 FCFA (about 13 EUR) and a 0.8 % merchant fee, monthly MoMo fees run about 6,100 FCFA — easily offset by fewer till errors that used to cost her up to 15,000 FCFA/month in discrepancies.

Is the MoMo QR expensive for the merchant?
Merchant fees range from 0 to 1.5 % in 2026 depending on account status. On an 8,500 FCFA basket that's at most ~130 FCFA per sale, with no change to hand back and no fake-note risk.
Static or dynamic for a small shop?
A static QR is enough to start: near-zero cost and 12-15 s per transaction. Move to dynamic once you exceed ~100 sales/day to remove entry errors and drop to 8-10 s.
How do I avoid fake-payment fraud?
Never release the product before the confirmation notification lands in your merchant app. An end-of-day reconciliation between the MoMo log and the till keeps discrepancies below 1 %.
Do I need a permanent connection?
The customer pays from their own data plan; on the merchant side a 3G smartphone is enough to receive confirmations. Keep a backup sign and a reconciliation notebook for network outages.
Can I combine two providers on one sign?
Yes, by showing two separate QR codes side by side. That pushes urban adoption past 80 % and avoids losing a sale over payment method.
