Background technology
As everyone knows; The burglary protection system for commodities that is used for supermarket etc. at present is " Electronic Article Surveillance "; Original text is " Electronic Article Surveillance ", is called for short " EAS ", and this system mainly is made up of three parts: the radio frequency detecting device; Demoder/decoding deck/nail-fetching device, soft label/hard label.
EAS system works principle: on commodity, paste soft label in advance or hard label (selecting different labels for use according to different commodity) is installed; The commodity of purchase of customer can be paid the bill at cashier under the normal condition, and at this moment the cashier can decode the commodity of band anti-theft tag or adopts nail-fetching device to unblank on decoding deck; If instead directly just go out market (for example theft of merchandise person) without the cash register passage, soft label or hard label through out-of-date, can make the radio frequency detecting device produce and report to the police in the antitheft door surveyed area, thereby realize the antitheft purpose.
In this system:
1, soft label/hard label (soft label is a disposable product, and hard label is reusable) sticks on the commodity or adopts to be bundled on the commodity usually, looks condition of merchandise and decides.
Soft label/hard label is actually " LC " oscillator (referring to that telefault and capacitor compose in parallel); Soft label adopts the aluminium foil flexible circuit to process; And hard label directly adopts copper cash and capacitor to process, and centre frequency is consistent with the radio frequency detecting device all to be 8.2MHz.
