The described device is part of a product theft prevention system and is used for deactivating resonance labels. It is intended for use in combination with a hand-held optoelectronic bar code reader (1), so as to permit the deactivation at the checkout of shops and stores of electronic resonance labels provided with a bar code and attached to products in a single operation and simultaneously with the determination of the bar-coded data. The deactivator has antennas (8, 9), which are located in a casing (11) fixable externally to the front end of the hand-held bar code reader (1) and which are constructed as ferrite antennas. As a result of the housing of the antennas (8, 9) and preferably all the high frequency-carrying parts (14, 15) of the deactivator in a separate casing (11), the deactivator can be used in combination with any random hand-held bar code reader, without any changes having to be made to the latter.
Device for use with a hand-held bar code reader for reading bar codes at a front end thereof, said device including means for deactivating resonance labels provided with a bar code, said device comprising a transmitting antenna for deactivating said labels and a receiving antenna for receiving signals transmitted by said labels, and a casing for receiving the antennas therein, said casing including means adapted to be externally fixed to a region adjacent to the front end of the hand-held bar code reader such that the bar code reader reads said bar code and the antennas cooperate with said labels, said antennas being constructed as ferrite antennas.
Device for use with resonance labels provided with a bar code, said device comprising:
A device for deactivating resonance labels each having a bar code, said device for use with a hand held bar code reader including a housing having a front end, said device comprising;
