At checkout, a cardholder can select a saved card using a digital wallet of their choice, for example Apple wallet, GPay, and so on. Eligible offers are displayed within the wallet environment. They select the preferred installment plan, review the terms and conditions, and place the order. Once the purchase is completed, they receive purchase confirmation from the merchant and installments plan confirmation from the issuer.
