Cards from every major bank can be paid from the same screen.
A customer with cash in hand and a due date tomorrow should not need a bank branch. One OTP at your counter closes the bill.

Plenty of card holders still earn and save in cash. When the statement arrives they either travel to a branch, or pay late and take the interest. Both are avoidable.
Credit card bill payment lets them hand over cash at your counter. You enter the card number, the customer confirms with an OTP on their own phone, and the payment posts to the card account.
Built so no card detail ever sits with you.
Cards from every major bank can be paid from the same screen.
The customer authorises on their own phone, so nothing sensitive stays at your counter.
Payments post to the card account quickly, usually well before the due date closes.
Handed over so the customer has proof until the card statement updates.
Typed from the customer's card, in their presence.
The amount the customer wants to pay against the outstanding.
Sent to their registered mobile number for authorisation.
Take the cash, hand over the receipt, and your commission is credited.
Card bills are usually thousands rather than hundreds, so the commission is worth the two minutes.
Statements arrive every month and the same customer returns on roughly the same date.
Card holders are a different group from your cash withdrawal customers, which widens your reach.
You need the card number, entered in the customer's presence. Nothing is stored at your counter after the transaction.
Limits depend on the issuer and the network. The panel shows the applicable limit before you confirm.
Usually the same day. The receipt reference is the proof until the issuer's statement reflects it.
Check that the customer's registered mobile number is the one they are carrying. If it is a different number, the payment must be made through their own bank.
Nothing extra to set up if your bill payment service is already on.
