WRITER, READER, AND EXAMINING METHOD

摘要

To provide an examining method capable of expediting customs clearance procedures including authenticity verification of brand-name products to thereby reduce the labor cost and capable of achieving paperless and low-cost procedures. A writing apparatus of a company manufacturing or selling brand-name products is used to send a company code, etc., encoded using an encoding key to an ID tag assigned to brand-name products. The ID tag stores the encoded company code, etc. An examining apparatus of an official who is responsible for examining the authenticity of the brand-name products receives the information sent from the ID tag, and decodes the received information using a decoding key. The decoded data and a pre-stored company code are compared to determine whether or not a match is found, and a determination result is output. When it is determined that the brand-name products are authentic and when an export license is granted, an employee or the like of a shipping company encodes the information described in a B/L and store the encoded information in the ID tag. The B/L information is read from the ID tag, if necessary, and is decoded using a decoding key.
