Zusammenfassung:	A backend system (160) configured to enroll a mobile merchant communication device (120) for performing a payment transaction with a mobile consumer communication device (110) is disclosed. The backend system (160) comprises a processing circuitry (141; 151) configured to generate a first electronic secret for the mobile merchant communication device (120). Moreover, backend system (160) comprises a communication interface (143; 153) configured to receive an enrollment request from the mobile merchant communication device (120), wherein the enrollment request comprises the first electronic secret for authorizing the enrollment request and a second electronic secret generated by the mobile merchant communication device (120). The processing circuitry (141) is further configured, if the enrollment request is successful, to generate personalization data for the mobile merchant communication device (120). The communication interface (143) is further configured to transmit the personalization data to the mobile merchant communication device (120) for enabling the mobile merchant communication device (120) to perform the payment transaction with the mobile consumer communication device (110) The communication interface (143; 153) is further configured to attest the integrity of the mobile merchant communication device (120) based on the second electronic secret using a challenge response procedure.
