The infrastructure story is incomplete without merchants
Many countries can now point to faster payment systems, growing account ownership, and improved digital rails. Yet cash still dominates at many small shops. The World Bank argues that the missing link is not access in the abstract, but merchant acceptance in the places where everyday commerce actually happens.
That matters because digital economies are built in routine transactions, not just in headline infrastructure launches. A payment rail can be nationally available and still economically weak if corner shops, informal merchants, transport operators, and neighborhood service businesses do not accept it in practice. Consumers only change habits when they can use digital payments in the places that define daily life.
Merchant acceptance is therefore a distribution problem as much as a technology problem. Devices, onboarding, fee design, settlement timing, training, and dispute handling all shape whether a merchant sees digital payments as helpful or disruptive. If any of those layers fail, the rail exists on paper but not as behavior.

Trust and usability determine whether rails get used
The World Bank’s companion piece on fast payments and digital ID reinforces the point from another angle. Speed alone is not enough. Users need confidence that they are paying the right person, resisting scams, and operating inside systems with clearer identity assurance. Without that trust layer, fast payments can amplify mistakes and fraud.
This is where digital identity becomes economically important. Good identity design reduces impersonation risk, improves merchant verification, and gives consumers a cleaner way to confirm who they are paying. That does not mean every payment system needs heavy identity friction. It means the trust layer must be strong enough that everyday users feel safe shifting routine transactions away from cash.
So the last mile of a cashless economy is not purely commercial or purely technical. It sits at the intersection of merchant onboarding, user protection, identity confidence, and practical trust. That is why many countries discover that payment adoption plateaus even after they launch faster rails.
This is where digital-economy policy gets real
For policymakers, the implication is straightforward: stop equating payment infrastructure availability with payment adoption. The harder work is in distribution, onboarding, incentives, identity, and dispute handling. That is what turns rails into habits.
For providers, the challenge is even more concrete. They must make acceptance worthwhile for merchants with thin margins and limited patience for operational complexity. Lower hardware costs, simpler QR or smartphone acceptance, faster settlement, and clearer fraud handling often matter more than abstract national-payments strategy.
The countries that solve this last mile will not just have faster payment systems. They will have more usable digital economies. In that sense, merchant acceptance is not a side issue. It is the operational test of whether a cashless ambition can survive contact with everyday commerce.
Frequently Asked Questions
Why is merchant acceptance called the last mile of a cashless economy?
Because consumers only change payment behavior when they can use digital tools in everyday commercial settings. If neighborhood merchants, transport providers, and small shops still default to cash, national payment rails cannot translate into habitual use.
What role does digital ID play in payment adoption?
Digital ID improves trust by helping users verify who they are paying and reducing impersonation or scam risk. That trust layer becomes especially important as faster payments make mistakes harder to reverse.
What should governments and providers prioritize after launching fast-payment rails?
They should focus on merchant onboarding, low-cost acceptance, fraud handling, and clear user protection. Those operational layers determine whether faster rails become real economic habits or remain underused infrastructure.
