Abstract

The invention relates to a mobile identification transmitter (10) of a security system for a keyless activation of a locking mechanism (43) of a motor vehicle (40), having a housing (11) in which an electronics unit (12) is disposed, having at least one transmitting and receiving unit (13), the transmitting and receiving unit (13) is in connection (42) with a connection unit in the motor vehicle, and where by means of the connection an identification test can be performed for determining the authorization of a user. According to the invention, the electronic unit (12) comprises a communication means (20) to enable a data transfer (25, 25′) to an external data device (30, 30′) only at a range of up to 10 cm.

Claims

1. A mobile identification transmitter of a security system for keyless activation of a locking mechanism of a motor vehicle, comprising

a housing, in which an electronics unit is disposed having at least one transmitting and receiving unit,

in which the transmitting and receiving unit has a connection with a connection unit in the motor vehicle, by means of which connection an identification test for determining the authorization of the user can be performed,

wherein

the electronics unit comprises a communication means

to allow a data transfer to an external data device only in a range of up to 10 cm.

2. The mobile identification transmitter according to claim 1, wherein

the communication means operates according to an NFC standard.

3. The mobile identification transmitter according to claim 1, wherein

the communication means comprises a transmitting means and a receiving means.

4. The mobile identification transmitter according to claim 1, wherein

the data transfer comprises at least one of a unidirectional and bidirectional receiving and transmitting of data.

5. The mobile identification transmitter according to claim 1, wherein

the communication means comprises

an energy absorbing passive mode, wherein data transfer can be performed by damping a received energy, and

an energy emitting active mode, wherein damping of energy emitted by the communication means in the external data device leads to a data transfer to the communication means.

6. The mobile identification transmitter according to claim 1, wherein

the communication means comprises an energy emitting transmitting mode for receiving and sending data.

7. The mobile identification transmitter according to claim 5, wherein

the data transfer to the external data device can be performed in at least one of the passive mode and the active mode and the transmitting mode.

8. The mobile identification transmitter according to claim 5, wherein

the communication means operates within a frequency range f which lies between 10 MHz≦

f≦

15 MHz, and in particular, that the communication means operates within a frequency range fat 13.56 MHz.

9. The mobile identification transmitter according to claim 5, wherein

the transmitting and receiving unit allows an information transfer to the connection unit at the motor vehicle up to a range of 300 m.

10. The mobile identification transmitter according to claim 5, wherein

the communication means is blocked during an activation of the transmitting and receiving unit.

11. The mobile identification transmitter according to claim 5, wherein

the transmitting and receiving unit is blocked during an activation of communication means.

12. The mobile identification transmitter according to claim 5, wherein

the mobile identification transmitter comprises a switch element, wherein by means of the switch element the transmitting and receiving unit or the communication means can be alternatively activated or blocked.

13. The mobile identification transmitter according to claim 5, wherein

the switching element is disposed in at least one of the electronics unit, in the housing and at the housing.

14. The mobile identification transmitter according to claim 5, wherein

the mobile identification transmitter comprises a display wherein at least one of, in particular, the data transfer and information related to the data transfer can be displayed by means of the display.

15. The mobile identification transmitter according to claim 14, wherein

the display further comprises at least one of:

a light emitting diode (LED), an organic light emitting diode (OLED), a liquid crystal display (LCD), a plasma display, a cathode ray tube, a Surface Conduction Electron Emitter Display (SED), and a field emission display (FED).

16. The mobile identification transmitter according to claim 14, wherein

at least one of the electronics unit the transmitting and receiving unit and the communication means further comprise at least one of the following technologies:

wireless LAN (IEEE 802.11), FireWire (IEEE
