POS SYSTEM AND POS SYSTEM CONTROL METHOD

摘要

Provided is a POS system that enables confirmation of the presence or absence of radioactive contamination of a product at the time a product is sold, which is the final stage in the distribution channel, and to do so without increasing the labor burden, and also provided is POS system control method. The POS system is provided with the following: a storage means (11) for storing a product code in association with a radioactivity threshold value determined for each product code; a barcode scanner (30); a radioactivity measuring unit (40) for measuring radioactivity of a product on the basis of the amount of radiation emitted from the product; a comparison means (21) for comparing the radioactivity threshold value corresponding to a product code read by the barcode scanner (30) and the radioactivity measurement value measured by the radioactivity measuring unit (40); and an alarm outputting means (60) for outputting an alarm in a case where the radioactivity measurement value exceeds the radioactivity threshold value. The radioactivity measuring unit (40) is disposed at a position where the radioactivity of a product is detected when the product is in a scan position A at which the product code is read by the barcode scanner (30).
