Method for triggering complementary actions implemented by a processing unit of an electronic device, said electronic device including a data memory, a program memory and a communication means cooperating with the processing unit and providing a determined mode of communication via a communication network, the communication means being connected to a payment collection peripheral in order to cooperate with the processing unit, the processing unit implementing a payment collection application method in order to execute an action in response to the provision of an item of setpoint data (C p) by said processing unit, the item of setpoint data (C p) being produced by a setpoint human-machine interface cooperating with the processing unit, said item of setpoint data (C p) expressing an interaction between a user and said interface, the payment collection application method not supporting the communication between said electronic device and the payment collection peripheral, said method for triggering complementary actions being characterized in that it includes: - a step for detecting the provision by the processing unit of the item of setpoint data (C p) using a subscription service proposed by the processing unit, said subscription service making it possible to provide said item of setpoint data to all the methods subscribed to said subscription service beforehand; - a step for searching in the data memory cooperating with the processing unit, for a record including the value of the item of setpoint data (C p); - if (102-y) the data memory includes such a record, said method includes: o a step for requesting the non-distribution of said item of setpoint data (C p) to the payment collection application method as well as to the other methods subscribed to said subscription service by the processing unit; o a step for causing the implementation by the processing unit of a determined complementary action consisting of: ▪ producing a control request (Rt) for said payment collection peripheral; ▪ triggering the sending of said control request (Rt) by the communication means to the peripheral, said request (Rt) including control data (I c); o a step for requesting the distribution of said item of setpoint data (C p) to the payment collection application method and other methods by requesting an appropriate service for distributing said item of setpoint data (Cp) from the processing unit once the complementary action is finished. - a step for detecting the provision by the processing unit of the item of setpoint data (C p) using a subscription service proposed by the processing unit, said subscription service making it possible to provide said item of setpoint data to all the methods subscribed to said subscription service beforehand; - a step for searching in the data memory cooperating with the processing unit, for a record including the value of the item of setpoint data (C p); - if (102-y) the data memory includes such a record, said method includes: o a step for requesting the non-distribution of said item of setpoint data (C p) to the payment collection application method as well as to the other methods subscribed to said subscription service by the processing unit; o a step for causing the implementation by the processing unit of a determined complementary action consisting of: ▪ producing a control request (Rt) for said payment collection peripheral; ▪ triggering the sending of said control request (Rt) by the communication means to the peripheral, said request (Rt) including control data (I c); o a step for requesting the distribution of said item of setpoint data (C p) to the payment collection application method and other methods by requesting an appropriate service for distributing said item of setpoint data (Cp) from the processing unit once the complementary action is finished. o a step for requesting the non-distribution of said item of setpoint data (C p) to the payment collection application method as well as to the other methods subscribed to said subscription service by the processing unit; o a step for causing the implementation by the processing unit of a determined complementary action consisting of: ▪ producing a control request (Rt) for said payment collection peripheral; ▪ triggering the sending of said control request (Rt) by the communication means to the peripheral, said request (Rt) including control data (I c); ▪ producing a control request (Rt) for said payment collection peripheral; ▪ triggering the sending of said control request (Rt) by the communication means to the peripheral, said request (Rt) including control data (I c); o a step for requesting the distribution of said item of setpoint data (C p) to the payment collection application method and other methods by requesting an appropriate service for distributing said item of setpoint data (Cp) from the processing unit once the complementary action is finished.
