The verdict in three sentences
In 2026, a mobile money QR code collects in 8 seconds versus 45 for a cash payment with change-making. It removes the physical till, secures the float and reconciles every sale instantly into your back office. For a high-throughput store, the gain is measurable: up to 20% more transactions at peak hours.
Static vs dynamic QR
Two QR families coexist in 2026, with distinct uses:
| Criterion | Static QR | Dynamic QR |
|---|---|---|
| Amount | Entered by customer | Auto pre-filled |
| Setup cost | Near zero | Till integration |
| Entry error | Possible | None |
| Reconciliation | Manual | Instant |
| Best for | Small shop | Restaurant, retail |
| Transaction fee | 0-1% | 0-1% |
The static QR (a sticker on the counter) suits a street vendor; the dynamic one, generated by the till with the exact amount, eliminates entry errors and automates accounting.
Speed and fees: the real gain
Comparison of collection modes for an average 3,500 FCFA (≈€5.30) ticket in Kigali:
| Mode | Time per transaction | Merchant fee | Error/theft risk |
|---|---|---|---|
| Cash | 45 s | 0% | High |
| Static QR (Airtel) | 12 s | 0-1% | Low |
| Dynamic QR (MTN) | 8 s | 1% | None |
| Card (POS) | 30 s | 1.5-2.5% | Low |
| Payment link | 25 s | 1% | Low |
The dynamic QR is 5.6 times faster than cash and costs less than a card POS. At peak, those 37 seconds saved per customer translate directly into shorter queues and extra baskets.

Koffi runs a fast-food in Kigali: 180 lunch tickets/day, average ticket 3,500 FCFA. In cash, each collection took 45 s; his queue jammed at 12 people at peak, losing about 25 discouraged customers/day. After switching to dynamic mobile money QR (8 s), hourly throughput rises 20%. He recovers 20 customers/day × 3,500 FCFA = 70,000 FCFA/day, over 1,800,000 FCFA/month. The 1% fee (18,000 FCFA/month) is trivial against the gain, and his cash float drops 60%, cutting theft risk.
FAQ
Is a Wave QR code expensive for the merchant? No: 2026 fees range from 0 to 1% depending on operator and volume, far below a card POS at 1.5-2.5%.
What's the difference between static and dynamic QR? Static asks the customer to enter the amount (error risk); dynamic pre-fills the exact amount from the till and reconciles automatically.
How much time is saved per transaction? You go from 45 s in cash to 8 s with dynamic QR, i.e. 37 seconds saved — decisive at peak.
Is reconciliation really instant? Yes with dynamic QR: each sale flows immediately into the back office, removing the end-of-day manual matching.
Do I need special equipment? No: a simple screen or sticker suffices. Dynamic QR needs a light integration with your till system, doable in a few days.
