When processing repeated operations on the keyboard of a mobile communication device, mainly at direct debits, used is a separate data carrier with a memory in which is stored at least one file with a sequence of keyboard orders of a macro type. Data carrier is energetically supplied contact-free by electromagnetic field of the mobile communication device while receiving the requiring order and, according to this order, chooses from the memory and encodes appropriate file with a sequence of keyboard orders. Data carrier sends the encoded file into the mobile communication device which decodes the received file and performs processes representing the keystrokes according to the sequence of keyboard orders. The invention also describes connection and data carrier to perform above described method where the data carrier consists of a processor, transmitting and receiving unit, block for transforming electromagnetic field and a memory to store a file of orders.
