First Claim
Patent Images
1. A method of outputting a magnetic field from an outputting element to a reading device, the method comprising:
- causing the outputting element to move in relation to the reading device while outputting a first magnetic field to the reading device in accordance with a first outputting mode of a plurality of outputting modes and further causing the outputting element to concurrently sense one or more parameters of the reading device;
determining, at the outputting element and based on the one or more parameters sensed, a second outputting mode of the plurality of outputting modes; and
causing the outputting element to, subsequent to the determining, output a second magnetic field to the reading device in accordance with the second outputting mode, the first and second magnetic fields representing the same information.

Abstract
A device for and a method of outputting a magnetic field which is selected according to the type of card reader into which the device is inserted. Different card readers have different reader head types and different number of reader heads, and different modes of outputting the magnetic field, usually with the same information contents, are selected in order to cater for different reader types. In one example, the sensing coils of different reader heads may have different angles to the swipe plane, so that different field line angles may be selected to adapt to the actual reader head.

9. An outputting element, comprising:
-
one or more field generators configured to output one or more magnetic fields to a reading device; one or more sensors; and a controller configured to control the one or more field generators to output a first magnetic field to the reading device in accordance with a first outputting mode of a plurality of outputting modes concurrently with receiving, from the one or more sensors, one or more parameters of the reading device that are sensed by the one or more sensors, determine, based on the received one or more parameters, a second outputting mode of the plurality of outputting modes, and control the one or more field generators, subsequently to the determining, to output a second magnetic field to the reading device in accordance with the second outputting mode, the first and second magnetic fields representing the same information. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
