1PAY (1.0.0)(2 APIs included)

1PAY is a step ahead in payment methods where payee/receiver selects a unique 1PAY-ID of his/her choice for payments method and has no need to remember his/her account number/IBAN. The option to self-select alpha or numeric or alphanumeric 1PAY-ID on a predefined format is convenient for payees/receivers to remember and share with payers/senders.

Members will now offer 1LINK 1PAY as an extension of funds transfers to their payees/receivers requesting them to set-up their 1PAY identifier (alias) which allows them a choice to create a single alias based on one of the below:

• Nick name • Mobile number • CNIC • Anything else that payees/receivers set.

Further, the same 1PAY identifier (alias) may be used at multiple Members (first come first serve basis) by the same payee/receiver to manage their financial transactions in a coordinated and efficient manner.

Payers/senders will only enter the payees/receivers 1PAY identifier (alias) and the query will be routed to 1LINK Directory service for translation to account details.

OTP Based Debit (1.0.0)(7 APIs included)

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.

1QR (1.0.0)(3 APIs included)

1QR is an innovative development over the existing 1IBFT service, that contributes convenience at customer’s end by transforming the way P2P and Retail payments are made. In case of a P2P transaction, the receiver shares the credentials in form of a QR, and the sender scans the QR to make the payment. Whereas, in the case of Retail payment, instead of swiping the card on POS, the customer just needs to scan the QR Code displayed on the counter via his/her mobile phone. 1QR potentially opens a new market of P2P and Retail transactions below the threshold of 10,000 PKR. Given the rise in trend of modern trade and ride-hailing services, 1QR if implemented can be a ‘game-changer’ for the Pakistani market.
