There is a small ritual that every Nairobi commuter knows. You hand the conductor a five-hundred shilling note for a fifty shilling fare. He looks at the note. He looks at you. And then he delivers the line: haijarudi — it will not come back to me.
The problem is not dishonesty. It is arithmetic. Change is heavy, it runs out at the worst possible moment, and on a moving vehicle with twenty passengers, reconciliation is guesswork. Mobile money did not invent this problem, but it addresses it more directly than anything that came before.
Why cash is expensive for operators
For a SACCO, cash fares create three separate costs:
- Float risk. Conductors carry large amounts of change and cash, often late at night.
- Reconciliation. Daily takings have to be counted, matched to trips and banked — work that consumes hours and invites disputes.
- Disputes. Passenger and conductor rarely disagree about the fare itself; they disagree about what was handed over.
Add dishonest passengers flashing a fake M-Pesa confirmation screen — a problem operators have publicly complained about — and the case for a verified digital payment is obvious.
The shift, in stages
Cashless fares are not a single switch. They arrived in waves. Safaricom's earliest matatu partnerships pushed M-Pesa as a fare option, and the COVID-19 period accelerated adoption sharply, with operator fleets signing up specifically to reduce physical contact. More recently, contactless card systems have been deployed across thousands of buses in Kenya, and SACCOs have begun offering them alongside M-Pesa so passengers can choose how to pay.
That second generation matters. Paying by card or by tapping a reader is faster than typing a till number, and it produces a verified record at the point of payment rather than a screenshot that can be edited.
The goal was never to make payment fancy. It was to make it verifiable.
What changes on board
When fares go digital, the conductor's job changes more than you would expect. Less time counting change means more time managing the door and the stage. Fares become transparent, which removes the daily argument about whether the price went up this morning. And operators get something they rarely had before: a clean record of what a vehicle actually earned on a given run — which is the foundation for everything from maintenance budgets to loan applications.
Why it is not finished
Cash has not disappeared, and it will not for a while. Coverage is uneven. Some routes have reliable connectivity, some do not. Older passengers are comfortable with cash. And any system that depends on a phone battery will occasionally fail at 9 PM.
The realistic picture is a hybrid: digital payments for most trips, cash as the fallback, and the two reconciled as cleanly as possible. For a commuter, that means the trend line is in the right direction — fewer haijarudi moments, fewer disputes, and a fare you can see before you board.
