Abstract:
PROBLEM TO BE SOLVED: To provide a POS system, a bar code scanner, and a method of controlling the POS system such that when articles are sold in a final stage of a distribution path, it is confirmed whether the articles are contaminated with radioactivity without increasing the operation load.SOLUTION: The POS system includes storage means 11 for relating and storing article codes specifying articles and radiation thresholds determined by the article codes; a bar code scanner 30 having a bar code read part 31 which reads an article code out of a bar code attached to an article and a radioactivity measurement part 32 which measures radioactivity of the article from the radiation dose from the article; comparison means 24 for comparing a radioactivity threshold corresponding to the article code read by the bar code read part 31 with a radioactivity measured value measured by the radioactivity measurement 32; and alarm output means 21, 22 of outputting an alarm when the radioactivity measured value exceeds the radioactivity threshold.
Abstract:
Price label system comprising a price label system server connected to transceivers adapted to communicate price label information to price labels using a communication protocol. A predetermined number of transceivers defines a sub-cell and each sub-cell is associated with a communication profile that defines communication protocols to be used when communicating with the price labels in that sub-cell.
