It would be the most successful in Singapore in terms of customer acquisition, and retention.
For those who do not live in Singapore, SafeEntry is “is a national digital check-in system that logs the names, NRIC/FINs and mobile numbers of individuals visiting hotspots, workplaces of essential services, as well as selected public venues to facilitate contact tracing efforts.”
The reason is simple – to development a successful wallet/mobile payment system, a high frequency use case is almost a must. Ideally a high frequency, low amount transaction type. (Otherwise your customer acquisition cost will become prohibitively high).
SafeEntry’s use case – checking in and out of every building – will be even better than the best current payment use case in use (Grab ride hailing) and best current theoretical use case (MRT/buses).
Each user will have to use SafeEntry multiple times a day, regardless whether you are taking train, bus, taxi, private hire car or your legs to reach your destination.
This is especially the case if Covid-19 is here to stay (which of course we hope not).
No marketing cost, no user retention issues.
Imagine how much it would cost (in both manpower, money and time) for a commercial wallet operator to acquire these many merchants.
Perhaps some interoperability with other, existing payment/wallet apps?
