UnionPay
China’s card scheme, and also a QR rail — Chinese customers use it both ways, and enabling only the card side leaves the other half unserved. It is the scheme Singapore merchants most often forget to enable.
Why it matters to a merchant
The one that is two things at once, and merchants regularly have one without the other. A counter that accepts UnionPay cards has not necessarily been enabled for UnionPay QR, and a customer holding the app rather than the card will find that out at the till. Confirming both is a single question at onboarding.
