A method of improving communications between a wireless proximity token (such as a radio-frequency card) and a proximity token reader. The method comprises: (a) detecting a position of the proximity token relative to the proximity token reader; (b) providing feedback to a user about the detected position of the proximity token relative to a desired position for satisfactory communication between the proximity token and the proximity token reader; and (c) repeating steps (a) and (b) until communication between the proximity token and the proximity token reader has been completed or a preset time interval has elapsed.
