| 摘要 |
The present invention relates to a method, a reading device and a system for transmitting data and/or energy between a reading device and a transponder unit. Via a first antenna coil of the reading device generating a first magnetic field data and/or energy are transmitted to the transponder unit. By means of a second antenna coil a second magnetic field with opposite sign is generated. Within a near field or communication range ( 12 ) of the reading device the second magnetic field is weaker than the first magnetic field. In a tap-proof range ( 13 ), i.e. outside the near field, the two magnetic fields have the same absolute value and cancel each other out due to the opposite signs.
