System and method for price verification in a retail environment
View Patent ↗A system for verifying a price associated with an item in a retail environment includes a price tag having an optical member that includes an optical characteristic that modifies an amount of optical energy that leaves the optical member relative to an amount of optical energy received by the optical member, and a price tag holder including an optical sensor having an emitter and a detector. The emitter is positioned to emit optical energy onto the optical member and the detector is positioned to receive optical energy leaving the optical member. A computing device in operable communication with the optical sensor is operative to determine whether the price tag is accurate based upon a comparison between the amount of optical energy received by the detector and the amount of optical energy emitted by the emitter.
1. A method for verifying accuracy of a price tag associated with an item in a retail environment, comprising:
emitting, by an optical emitter, optical energy onto an optical member of a price tag, a transmissive member or a reflective member of the optical member having a transmissivity or reflectivity modifying an amount of optical energy leaving the optical member relative to an amount of optical energy received by the optical member;
detecting, by an optical detector, the amount of optical energy leaving the optical member; and
receiving, by a controller, an indication of the detected amount of optical energy and determining a price class or version of the price tag based upon a comparison of the amount of optical energy detected by the optical detector and an amount of optical energy emitted by the optical emitter, and determining whether the price tag is accurate based upon a comparison of the determined price class or version and a scheduled price class or version assigned to the item in the retail environment.
2. The method of claim 1 , wherein the optical member includes the transmissive member having the transmissivity modifying the amount of optical energy leaving the optical member relative to the amount of optical energy received by the optical member.
3. The method of claim 1 , wherein the optical member includes the reflective member having the reflectivity modifying the amount of optical energy leaving the optical member relative to the amount of optical energy received by the optical member.
