Frequency Identification) A data carrier is a battery-less data carrier that has the function of transmitting and receiving signals such as commands and data to and from an input / output device (reader / writer) in a contactless manner. When the antenna enters the effective electromagnetic wave zone radiated by the antenna, the antenna provided in the RFID data carrier generates an induced electromotive force, and the power is activated by the power to detect a command and data signal from the input / output device. The data is stored in the memory in accordance with the signal, or the data stored in the memory is transmitted to the input / output device, and the personal identification data is stored in the memory so as to be used when entering and leaving (entry and exit). Individual identification becomes possible. In such a configuration, by fitting the annular antenna to the finger, the RFID data carrier can always be carried directly and carried around, so that excellent portability can be obtained and loss can be prevented. it can. Further, since the IC chip can be hermetically embedded in the synthetic resin exterior body, excellent waterproofness can be obtained, and it is not necessary to remove the finger from the finger even when the hand is wet or immersed in water. . Here, if the antenna is constituted by a single annular antenna wire having both ends connected to an exterior body, the annular antenna wire can be used as a loop antenna, and both ends of the annular antenna wire can be used. Since the parts can be integrally fixed to both side edges of the exterior body, excellent rigidity can be provided. Further, if the antenna is constituted by a coil-shaped antenna wire having both ends connected to an exterior body, the number of turns as a loop antenna can be set, so that adjustment of induced electromotive force and communication distance is facilitated. . Further, the antenna may be constituted by a pair of arcuate antenna wires each having one end connected to a centrally disposed exterior body and the other end being an open end. In this case, since the diameter can be changed according to the thickness of the finger to be fitted, versatility that can be used as a multi-size is obtained. Also, since a half-wave dipole antenna in which the electric field intensity becomes zero at the open end can be applied, there is an advantage that a sine wave current can be efficiently induced. Further, the antenna may be constituted by a single substantially C-shaped antenna having one end connected to the exterior body and the other end being an open end. In this case, as above,
