The verdict in three sentences
Payment risk differs by method: cards expose you to chargebacks (a dispute that force-refunds the customer), while mobile money has none but suffers sim swap and phishing. In 2026, e-commerce card chargeback rates in Africa run around 0.6 to 1.2 % of volume, versus 0.2 to 0.5 % mobile money fraud. The right defense isn't choosing a method, but applying the right controls: OTP, server-side webhook confirmation, never validation on a screenshot.
Two opposite risk models
On cards, power sits with the buyer: they can dispute a transaction with their bank months later, and the merchant must prove legitimacy or face a force-refund plus dispute fees. On mobile money, payment is pushed by the customer via their secret code: once confirmed server-side, there's no chargeback. The risk therefore shifts to entry fraud: fake payment proof, sim swap, phishing of the confirmation prompt.
| Criterion | Bank card | Mobile money |
|---|---|---|
| Loss mechanism | Chargeback (force-refund) | Entry fraud |
| Dispute/fraud rate | 0.6 to 1.2 % | 0.2 to 0.5 % |
| Who bears the loss | The merchant | The merchant (if poorly verified) |
| Resolution delay | 30 to 90 days | Immediate to a few days |
| Fixed cost per dispute | EUR 15-25 + goods | Low if webhook verified |
*2026 ballpark; rates vary by sector and anti-fraud policy.*
Anatomy of mobile money fraud
Without chargebacks, mobile money isn't risk-free. Three attacks dominate: the fake proof (the customer shows a screenshot of a payment never received), the sim swap (taking over the number to drain a wallet), and prompt phishing (the fraudster pushes a misleading confirmation prompt). The counter is technical and simple: never deliver on a screenshot, always wait for server-side webhook confirmation.
| Fraud | Target | Main counter |
|---|---|---|
| Fake proof (screenshot) | Gullible merchant | Mandatory server webhook confirmation |
| Sim swap | Customer wallet | OTP + SIM-change alert |
| Prompt phishing | Customer | Education + clear merchant label |
| Mule account | Marketplace payout | Vendor KYC, caps |
*Most mobile money losses come from manual validation on a screenshot, 100 % avoidable.*
The golden anti-fraud rules
Three rules eliminate most of the risk, whatever the method. One, systematic OTP verification on sensitive operations. Two, server-side confirmation via webhook: payment status is authoritative only when your server receives the operator's signed notification, never the customer's screen. Three, no validation on a screenshot, ever, even for a trusted customer. These three rules bring residual fraud under 0.2 %.
Mini case study
Amina runs an online cosmetics store in Dakar with 8,000,000 FCFA volume/month. She accepted card and mobile money, and validated some urgent orders on a WhatsApp screenshot. On cards, she suffered a chargeback rate of ~0.9 %, i.e. 72,000 FCFA/month in losses plus dispute fees. On mobile money, fake proofs still cost her ~0.4 %, i.e. 32,000 FCFA/month.
She enforces server webhook confirmation (ending screenshot validations) and OTP. Mobile money fraud drops to ~0.1 % (~8,000 FCFA/month) and she disputes card chargebacks better with delivery proof, bringing card loss to ~0.5 %. Total savings: from 104,000 to ~48,000 FCFA/month, i.e. ~672,000 FCFA/year recovered, from a single technical discipline.

FAQ
Is mobile money really chargeback-free?
Yes: payment is pushed by the customer via their secret code, there's no bank dispute mechanism as on cards. Risk shifts to entry fraud, avoidable by server webhook confirmation.
Why never validate on a screenshot?
A screenshot is faked in seconds. The only reliable proof is the signed webhook notification your server receives from the operator. Delivering on a screenshot is the top cause of mobile money loss.
How much does a card chargeback cost?
Beyond the lost goods, expect a fixed dispute fee of about EUR 15 to 25 per case, and a 30 to 90 day resolution during which funds are held. A rate above 1 % can threaten your merchant account.
Is OTP enough to secure payment?
OTP protects against impersonation, but combine it with server webhook confirmation and caps. On a marketplace, add vendor KYC to block mule accounts that divert payouts.
Which method should I favor to limit losses?
Both, well configured, are safe. Well-verified mobile money has a lower fraud rate (0.2-0.5 %) than card chargebacks (0.6-1.2 %), but cards stay essential internationally. What matters is control, not an exclusive choice.
