Abstract

A device ( 100 ) comprising a Radio Frequency Identification transponder and means for selectively controlling the Radio Frequency Identification communication, the device ( 100 ) comprising: a first, internal, electromagnetic shield fixed on one side of the Radio Frequency Identification transponder's antenna and a second, internal, electromagnetic, movable shield ( 180 ) on the other side of the Radio Frequency Identification transponder's antenna wherein the device ( 100 ) comprises an internal actuator ( 170 ) configured to operate a movable mechanism ( 150 ), influencing the position of the movable shield, such that when the internal actuator is in a first position, the movable shield is in a first position allowing communication with the Radio Frequency Identification transponder and when the internal actuator is in a second position, the movable shield is in a second position, in which it blocks all contactless communication with the Radio Frequency Identification transponder.

First claim

The invention claimed is:

1. A device comprising a Radio Frequency Identification (RFID) transponder and means for selectively controlling the Radio Frequency Identification transponder communication, the device comprising:
a first, internal, electromagnetic shield fixed on one side of the Radio Frequency Identification transponder's antenna; and
a second, internal, electromagnetic, movable shield on another side of the Radio Frequency Identification transponder's antenna;
wherein the device further comprises an internal actuator configured to operate a movable mechanism, influencing a position of the movable shield, such that when the internal actuator is in a first position, the movable shield is in a first position allowing communication with the Radio Frequency Identification transponder and when the internal actuator is in a second position, the movable shield is in a second position, in which the movable shield blocks all contactless communication with the Radio Frequency Identification transponder
wherein the internal actuator is a lever actuator and the movable mechanism is a lever,
the lever pivots at the lever's fulcrum and includes a first engaging mandrel and a second engaging mandrel;
the lever actuator has an elongated opening;
the movable shield has an elongated opening;
wherein the first engaging mandrel slidably engages the elongated opening of the movable shield; and
wherein the second engaging mandrel slidably engages the elongated opening of the lever actuator;
such that the movable shield may be moved between said first and said second positions.

2. The device according to claim 1 wherein the lever is right angle lever is used, the right angle lever including two perpendicular rods.

3. The device according claim 1 wherein the first engaging mandrel and the second engaging mandrel are situated on the same side of the lever and in proximity to the opposite ends of the lever.

4. The device according to claim 1 wherein the device comprises a push-back mechanism configured to return the internal actuator that has been pushed, to the internal actuator's initial position, when said push-back mechanism has been released.

5. The device according to claim 1 wherein the movable shield and internal actuator are toothed and engage each other so that a rotation of the internal actuator results in rotation of the movable shield.

6. A reader device for a contactless communication device, the contactless communication device comprising:
a Radio Frequency Identification (RFID) transponder and means for selectively controlling the Radio Frequency Identification transponder communication;
a first, internal, electromagnetic shield fixed on one side of the Radio Frequency Identification transponder's antenna and
a second, internal, electromagnetic, movable shield on another side of the Radio Frequency Identification transponder's antenna
wherein the contactless communication device further comprises an internal actuator configured to operate a movable mechanism, influencing a position of the movable shield, such that when the internal actuator is in a first position, the movable shield is in a first position allowing communication with the Radio Frequency Identification transponder and when the internal actuator is in a second position, the movable shield is in a second position, in which the movable shields blocks all contactless communication with the Radio Frequency Identification transponder;
wherein the reader device comprises:
a holder configured to hold the contactless communication device;
a Radio Frequency Identification transponder configured to communicate with the Radio Frequency Identification transponder of the contactless communication device;
a controller, which is communicatively connected to an actuation means selectively engaging the internal actuator of the contactless communication device
wherein the internal actuator is a lever actuator and the movable mechanism is a lever,
the lever pivots at the lever's fulcrum and includes a first engaging mandrel and a second engaging mandrel;
the lever actuator has an elongated opening;
the movable shield has an elongated opening;
wherein the first engaging mandrel slidably engages the elongated opening of the movable shield; and
wherein the second engaging mandrel slidably engages the elongated opening of the lever actuator;
such that the movable shield may be moved between said first and said second positions.
