Abstract
It is provided a method for communicating with an electronic lock (4). The method comprises: establishing (40) a communication channel (10) with the electronic lock (4) based on inductive coupling, wherein the lock communication device (2) emulates a contactless smartcard; receiving (42) a read request (20) from the electronic lock over the communication channel; transmitting (44) a read response to the electronic lock over the communication channel, the read response comprising a command; and repeating (48), for at least one more iteration, the receiving (42) a read request and transmitting (44) a read response for a plurality of commands. In at least one of the iterations, the read response comprises an indicator that the electronic lock may write data back, upon which the at least one iteration also comprises: receiving (46) command response data over the communication channel, the command response data being based on the command of the read response.
