During the installation of Tap on Mobile, the merchant is asked to also install a Worldline Tap on Mobile Pinpad app, which is necessary for enabling PIN authorization (for high-value payments). This is one of the product’s USPs – supporting PIN on Glass.

You can perform the following actions on a transaction via Worldline Tap on Mobile: purchase, cancellation (reversal) and refund (from 0 to 100% of the transaction).

DCC is currently supported with version 4.1.39

The transaction history can be viewed on the Worldline Tap on Mobile app and also on the online portal. There are no limitations to the transactions that are shown.

Each terminal ID has its own transaction history. It is not possible to hide the transaction history in the app.

A digital payment receipt can be sent via email, or the cardholder can scan a QR code to receive the receipt.

Options are as follows:

Standalone:

• Use the receipt provided within the app (email or QR-Code). If the merchant wants to print it, they can email it to a PC or similar device and print it or scan the QR-Code and print the Webpage,

• Use the receipt that the cash register provides (in this case, Tap on Mobile is only used as a payment terminal).

Simple integration (WPI):

• Use the receipt provided within the app (email or QR-Code). If the merchant wants to print it, they can email it to a PC or similar device and print it or scan the QR-Code and print the Webpage,

• (A cash register does not make sense in a WPI integration case - the goods are registered in a merchant app, not in a cash register),

• Print the receipt from the merchant app (WPI returns all fields needed to create a receipt, on top of that the merchant has the list of goods from their app, possibly some loyalty details, etc.),

• Create their own receipt solution based on the information provided by WPI.
