Abstract: A device includes a storage unit that stores generated challenges which are challenges previously generated, a determination unit that determines whether a newly generated challenge matches any of the generated challenges or not, an output unit that outputs the newly generated challenge as an unused challenge when the determination unit determines that the newly generated challenge does not match any of the generated challenges, and a registration unit that stores the newly generated challenge as a new generated challenge in the storage unit when the determination unit determines that the newly generated challenge does not match any of the generated challenges.

Abstract: According to a first aspect, there is provided a container with an electronic tag that can efficiently manage information on many containers, and is excellent in heat resistance or others, simple in structure and easy in manufacturing, wherein a bottom of a glass container body and the electronic tag are protected against mechanical impacts. According to a second aspect, there are provided a container with an electronic tag that can manage information on a product in the container and so forth without spoiling the appearance of the container accommodating the product and an RFID system using the container. In the first aspect, the container with the electronic tag includes a glass container body, a glass bottom cover member attached to a bottom of the glass container body so as to cover the bottom, and an electronic tag placed between the glass container body and the glass bottom cover member.
