1. An active radio tag comprising:
- a storage unit having stored therein a tag ID;
a transmission unit that transmits, by radio, the tag ID in a predetermined signal form;
a card holder having the storage unit and the transmission unit built therein and including a card placement section in which a card is to be placed; and
a detection unit that detects a card placed in the card holder, wherein when the detection unit detects a card, transmission of the tag ID is allowed and when the detection unit does not detect a card, transmission of the tag ID is prohibited,wherein the card holder includes an operation section, the transmission unit transmits the tag ID in different signal forms for different cases, a case in which the operation section is operated and a case in which the operation section is not operated, when the operation section is operated, if the detection unit detects a card, then transmission of the tag ID in a first signal form is allowed, and if the detection unit does not detect a card, then transmission of the tag ID in the first signal form is prohibited, and when the operation section is not operated, regardless of whether there is a card, transmission of the tag ID in a second signal form is allowed.

Abstract
An active radio tag including a card holder. The card holder has built therein a memory having stored therein a tag ID and a transmission unit that transmits the tag ID by radio. In addition, the card holder includes a card placement section in which a card is to be placed and a card detection switch that detects the card. Only when the placement of the card in the card placement section is detected by the card detection switch, the radio tag is activated and the tag ID is transmitted.

2. An active radio tag comprising:
-
a storage unit having stored therein a tag ID; a transmission unit that transmits, by radio, the tag ID in a predetermined signal form; a card holder having the storage unit and the transmission unit built therein and including a card placement section in which a card is to be placed; a detection unit that detects a card placed in the card holder; a reading unit that reads card information stored in the card detected by the detection unit; and a determination unit that checks the card information read by the reading unit against the tag ID to determine whether the card is a right card, wherein when the detection unit detects a card, if the determination unit determines that the card is right, then transmission of the tag ID is allowed, and if the determination unit determines that the card is not right, then transmission of the tag ID is prohibited, and wherein when the detection unit does not detect a card, transmission of the tag ID is prohibited, wherein the card holder includes an operation section, the transmission unit transmits information on the tag ID in different signal forms for different cases, a case in which the operation section is operated and a case in which the operation section is not operated, when the operation section is operated with a card being detected by the detection unit, if the determination unit determines that the card is right, then transmission of the tag ID in a first signal form is allowed, and if the determination unit determines that the card is not right, then transmission of the tag ID in the first signal form is prohibited, and when the operation section is not operated, regardless of whether there is a card and whether the card is right, transmission of the tag ID in a second signal form is allowed.
