Description
Technical field
The present invention relates to acoustic magnetic anti-theft label decoding technique fields more particularly to a kind of frame-type acoustic magnetic anti-theft label to decode
Device and method.
Background technology
Existing decoder is planar structure, and store clerk takes label to known after items scanning price bar code
One smaller position of decoder plane surface in road（Such as there was only 3-5 cm height）, trigger decoder sends out a high frequency
Alternating current magnetic field will deactivate after the bias slice demagnetization in label.But with popularizing for mobile-phone payment so that customer oneself barcode scanning is purchased
Object is achieved.When customer oneself barcode scanning is done shopping, customer does not have motivation or market not to want that customer is allowed to know how specially
The particular surface that the label being attached on commodity one by one is taken to conventional decoder very little deactivates.Therefore, label is possibly can not
Degaussing and cause the alarm on doorway to send out alarm, by false alarm when customer being caused to leave market, cause unnecessary trouble,
Influence shopping experience.
Invention content
The present invention to solve the above-mentioned problems, provides a kind of frame-type acoustic magnetic anti-theft label decoder and method, frame
Region of the inside for efficient decoding significantly increases, and is that one kind can be used for mobile phone self-help payment or store clerk by whole bag
The deactivated device and method of activated state audio magnetic label in commodity.It is frame decoder, the commodity hand that customer will choose
It is all put into after machine self-checkout in framework or the commodity for paying money is all put into the shopping bag in framework by store clerk
In, the alternating current magnetic field that is generated in framework deactivates the acoustic magnetic anti-theft label on all commodity being put into, avoid the occurrence of customer without
Method or do not know how correctly to acoustic magnetic anti-theft label deactivate or shop assistant miss individual label deactivations the case where.
To solve the above-mentioned problems, the present invention is achieved by the following scheme：
