The hardest case for a payment scheme is the shop till. We built that case first. The buyer taps the phone and approves the payment in the banking app. The whole payment takes under 3 seconds. The tap uses NFC. No part of the flow needs proprietary software. In EU terms this is IP@POI, instant payment at the point of interaction.
A shop can put a sign like this on its door. Under the sign, the shop can show the banks whose apps pay with a tap.
Illustration only. The bank logos are examples of how a shop could show them. They do not mean that these banks take part in instaSEPA.
Other payments use the same parts and are easier to build. Here are six examples.
A SEPA Direct Debit can fail if the account has too little money on the due date. The creditor can then send a Request-to-Pay to the same account. If the payer approves it in the banking app, SCT Inst moves the money in seconds.
Request-to-Pay to the payer's IBAN, paid by SCT Inst.
A service can bill a customer each month with an account-to-account payment. It sends one Request-to-Pay for each period. The customer approves the 1st one in his banking app. Then if the customer selects "auto approve future RTP from this IBAN" in his banking app the subscription is collected automatically each month via auto-approved SRTP.
One Request-to-Pay per billing period.
The customer taps the phone on the cash machine and confirms the amount on the phone. A few seconds later, the money reaches the ATM operator. Then the machine pays out.
NFC tap with a disposable vIBAN, then Request-to-Pay and SCT Inst.
Each invoice gets its own virtual IBAN. The customer pays by SCT Inst, and the money arrives in seconds. The accounting system uses the virtual IBAN to match each payment to its invoice automatically.
One vIBAN per invoice, and a Request-to-Pay with the invoice reference.
Some purchases are large, for example a car service, a bike, a home appliance or a car. A card limit can be too low for an amount like this. After the buyer approves the Request-to-Pay, SCT Inst moves the full amount in seconds, within the buyer's own transfer limit. Before that, the buyer's bank checks that the seller's name matches the IBAN.
Request-to-Pay with Verification of Payee, paid by SCT Inst.
A town hall sends a Request-to-Pay for property tax or a parking fine. The citizen pays from the banking app. The payment arrives with its reference, so the town hall books it at once. At the counter, the citizen can also pay with a tap.
Request-to-Pay with a structured reference, or an NFC tap at the counter.
Any case that card schemes cover today can work with the same experience for the user. The money moves by SEPA Instant Credit Transfer. The other parts are:
