A method for configuring a mobile Point-of-Sales (mPOS) application for executing a transaction includes: installing an application frontend of the mPOS application on a terminal device connected to a communication network; installing an application backend of the mPOS application on an edge cloud server of the communication network; configuring the application frontend to act, upon launch, as an I/O interface and to communicate with the application backend via a secure connection provided by the communication network; and splitting I/O drivers comprised by computer program code of the mPOS application into a low-level driver executed on the terminal device as part of the I/O interface and a high-level driver executed in the application backend at the edge cloud server.
