Android Pay is an in-store and in-app payment method, providing a secure process for consumers to purchase goods and services. In-store purchases are done by using Near Field Communication (NFC) technology built into the Android Smart phone with any NFC-enabled terminal at the retail POS. For in-app purchases, the consumer need only select Android Pay as the payment method in your application. You will need to modify your application to use Android Pay as a payment method.
Vantiv supports two methods for merchants to submit Android Pay transactions from Mobile applications to the eComm platform. The preferred method involves you sending certain Vantiv specific parameters to Google. The response from Google® includes a Vantiv paypageRegistrationId, which you use normally in you payment transaction submission to Vantiv. With the alternate method, you receive encrypted information from Google, decrypt it on your servers, and submit the information to Vantiv in a payment transaction.
