Product information update apparatus

摘要

An ultra-high frequency radio frequency identification reader-writer wirelessly sends a product information signal to an ultra-high frequency antenna. The ultra-high frequency antenna sends the product information signal to an ultra-high frequency side dual interface memory unit. The ultra-high frequency side dual interface memory unit utilizes an energy of the product information signal to update a product data corresponding to the product information signal. When a processing unit and a high frequency side dual interface memory unit are driven, the processing unit fetches the product information signal from the ultra-high frequency side dual interface memory unit. The processing unit sends the product information signal to the high frequency side dual interface memory unit. The high frequency side dual interface memory unit updates the product data corresponding to the product information signal.
