PayXpress V4
This version of our in-store payments app was made available in January, 2025. Here is what’s new:
We now support PayXpress on the landscape-oriented Sunmi P2 Smartpad:
New languages can be used for the interface so that depending on where you are, you and your shoppers can transact in the local language. Catalan, German, French, Italian, English, and Spanish screens are available:
You can now remotely access a sales ticket in our Central Backoffice. Therefore you can access and print any sale, refund or cancellation ticket-—in both customer and merchant format—via the online portal. See Functionalities of PayXpress | Get a duplicate ticket remotely via Central Backoffice for full details.
Also, you do not need to be in front of the POS device to perform a refund. You can do this remotely, too. See Functionalities of PayXpress | Full or partial refunds remotely via Central Backoffice for a full explanation.
Our devices can now, by default, communicate with cash registers via the Concert protocol (v3.2). So, your cash register can send the payment total to our POS, which displays that amount on screen. Feel free to learn more about how the protocol works here.
