American Express specifications sunset
To guarantee that the payment terminals certified to accept ExpressPay contactless payments meet the latest specification enhancements, American Express has recently released a document announcing the progressive sunset dates of the previous ExpressPay versions.
According to the document, the certification renewal of a terminal supporting ExpressPay version 4.0.2 will no longer be accepted as of October 31st 2023.
And as of this same date, new readers submitted to the initial certification of Amex shall support the latest version of the specification, v4.2, published last november.
Alcineo supports payment terminal providers during the development of their product, and our team closely follows the specification evolutions to fit our customers’ needs.
