In your consumer app, where the NFC feature is enabled in the device. The consumer initiates a payment by tapping an NFC device at the merchant site. The App will initiate a push payment request presenting the token key and payment details(acquirer account, payment amount) to VTS. The VTS will check the eligibility with Issuer(Consumer Bank) and if approved, initiates the payment transfer to the acquirer bank account. Upon successful response from the acquirer, the merchant is notified by Visa and also the consumer is notified. The API for NFC Payment is similar to mobilepushpayment API in mVisa.
@Diana, Please correct me if my flow mentioned above is incorrect.
