Alcineo contactless payment suite includes the latest version of American Express specification for contactless terminals : Expresspay 4.1.
Do not hesitate to contact us if you consider updating your products with Expresspay 4.1
The MCL kernel developed by Alcineo now integrates the EMV bulletin 261 optional implementations rules. Although the bulletin is effective since January 2022, the implementation is optional according the latest test plan edited by Mastercard.
Our team chose to integrate the bulletin to our Ma-Kardia kernel, so our customers can integrate the solution to their terminals supporting Mastercard contactless transactions.
