OTP Based Debit 1.0.0
The OTP Based Debit service is a payment method that is designed to run on banking networks. It allows customers to pay for transactions by debiting directly from their bank account, as opposed to processing through a card brand or scheme.
This service is being introduced by 1LINK as a standalone transaction set for its Members and Affiliates where customers can link their bank accounts to a payment acquiring channel, and subsequently make payments using their bank accounts through a direct debit.
The account verification and the payment debit are made secure using an OTP mechanism, which is sent to customer for authorization of each transaction request by the Issuer.
