Abstract
Described is a method for guiding a user for positioning a first RFID-enabled device relative to a second RFID-enabled device for allowing a robust RFID communication between the two RFID-enabled devices. The method includes placing the first RFID-enabled device to a first position relative to the second RFID-enabled device; receiving, by the first RFID-enabled device, when being located at the first position, a first RFID signal transmitted by the second RFID-enabled device; measuring, by the first RFID-enabled device, a first signal strength of the first RFID signal; placing the first RFID-enabled device to a second position relative to the second RFID-enabled device; receiving, by the first RFID-enabled device, when being located at the second position, a second RFID signal transmitted by the second RFID-enabled device; measuring, by the first RFID-enabled device, a second signal strength of the first RFID signal; determining, based on the first signal strength and on the second signal strength, a movement indication for a movement of the first RFID-enabled device towards a target position, at which there is expected a target RF coupling strength between the two RFID-enabled dev…
