How does an instant payment work?
The payer approves a transfer in their banking or wallet app, often by scanning a QR code or entering an alias such as a phone number or tax ID. The payer’s bank debits the account and the scheme settles the transfer to the payee’s bank within seconds, at any hour. For a merchant, the provider generates a payment request or reference, receives confirmation from the scheme and notifies the merchant. Payouts run the same way in reverse, from the merchant’s account to the customer’s.
Why do instant payments matter for merchants?
In many markets they are now how people pay. Expansión reports that Mexico’s SPEI processed more than 7.3 billion transfers in 2025, and PIX plays a similar role in Brazil. In the euro area, the Instant Payments Regulation required providers to be able to receive instant payments from 9 January 2025 and send them from 9 October 2025, at no higher charge than standard transfers. As an illustrative example: an online store whose card payments approve at 65% in a market adds an instant payment option that completes 85% of initiated payments. Moving 4,000 of 10,000 monthly payments to it adds about 800 completed payments.
What are the risks?
Payments can fail on name or tax ID mismatches, invalid aliases, bank-side limits and provider timeouts. Payouts are final, so a duplicate is hard to recover, and some schemes allow fraud returns after the fact. Each scheme has its own limits, operating rules and restricted merchant categories, so availability for a given merchant category varies by provider.
Where does Omno use it?
Omno connects instant payment methods such as PIX and SPEI through its PSPs for Pay-In and Pay-Out, shows them in the hosted checkout according to eligibility rules, and reports their final statuses by webhook.
