The verdict in three sentences
A Wave QR code collects an in-person payment in under 10 seconds at about 1 % fee, with no POS to buy or rent. The classic bank terminal costs around 30,000 CFA to buy plus a card commission of ~1.8 %, and requires a banking contract. For a small shop, a printed static QR is enough; for high volume, a dynamic QR generated by the till eliminates amount errors.
Static QR vs dynamic QR
Two modes coexist. The static QR is a printed image shown at the counter: the customer scans and types the amount themselves. The dynamic QR is generated per sale with the amount already filled in, which prevents entry errors and speeds up the queue.
| Criterion | Static QR | Dynamic QR |
|---|---|---|
| Amount | Typed by customer | Pre-filled by till |
| Setup cost | Near zero (printing) | Till/API integration |
| Error risk | Medium | Low |
| Time per transaction | 10 to 15 s | Under 10 s |
| Ideal for | Small shop | High volume |
| Reconciliation | Manual | Automatic |
The static QR suits an artisan or small shop. As soon as volume rises, the dynamic QR linked to the till saves time and makes accounting reliable.
Cost compared: QR vs bank POS
The real advantage of the QR is the absence of hardware and a low transaction fee. Here is the 2026 order of magnitude for a shop collecting 3,000,000 CFA per month.
| Item | Wave QR | Bank POS |
|---|---|---|
| Initial hardware | 0 CFA | ~30,000 CFA |
| Fee per transaction | ~1 % | ~1.8 % + card |
| Monthly cost on 3,000,000 CFA | ~30,000 CFA | ~54,000 CFA |
| Banking contract | Not required | Required |
| Merchant confirmation | Instant (app) | POS receipt |
| Credit delay | Fast (wallet) | T+1 to T+2 |
On 3,000,000 CFA of monthly turnover, the QR saves about 24,000 CFA/month in fees, plus the avoided terminal cost. In Nairobi, the M-Pesa QR (Lipa na M-Pesa) follows the same logic and cuts the queue at peak hours.

Mini case study
Fatou runs a tea room in Dakar with 60 tickets a day, average basket 2,500 CFA, i.e. about 4,500,000 CFA/month. With a POS at 1.8 %, she would pay about 81,000 CFA/month in fees plus 30,000 CFA for the terminal. With a dynamic Wave QR at 1 %, her fees drop to 45,000 CFA/month, with no hardware. Saving: about 36,000 CFA/month, over 430,000 CFA/year, while confirming every payment instantly on her phone.
FAQ
Does the Wave QR really charge 1 % fee? As a 2026 order of magnitude, merchant QR collection runs around 1 %, versus ~1.8 % plus commission for a card via POS.
Does the merchant need a smartphone? Yes, the merchant app confirms each payment in under 10 seconds. The customer scans with their own phone.
Static or dynamic, which to choose? Static (a printed image) is enough for low volume; dynamic, linked to the till, eliminates amount errors and suits more than a few dozen tickets a day.
What does a bank POS cost by comparison? About 30,000 CFA to buy plus a card commission around 1.8 % and a banking contract, versus zero hardware for the QR.
Does the credit reach the wallet quickly? Yes, the amount appears almost immediately in the merchant wallet, versus a T+1 to T+2 delay for a classic bank POS.
