You can show an image on the display of the payment terminal, for example an advertisement, or a special offer that is generated by your POS app. By showing an image, you can use your terminal to increase shopper loyalty, or for marketing purposes.<\/p>\n

The image can be a PNG, JPEG, GIF, or BMP file that you convert to Base64.<\/p>\n

\n

The terminal shows the image during the time you set in the request. If you do not set a time-out, the image continues to be shown until you send another request. For example, a payment request, a request for a different image, or a request to show the standby screen<\/a>.<\/p>\n<\/div>\n

The following illustrations show an image on a portrait, small portrait, and landscape display.<\/p>\n
