When a person passes by the external apparatus performing writing or reading data, data communication is performed between a recording medium and the external apparatus and, since the recording medium is used in the state mounted on a wrist, it can easily approach the external apparatus and the writing and confirmation of data can be performed by the bracelet-shaped non-contact recording medium.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bracelet-type non-contact recording medium that is directly attached to a wristband and performs non-contact data communication with an external device.

(b) Conventional Technology ID cards with personal identification data recorded thereon, commuter passes recorded with expiration dates, and the like have been used as devices for automatically managing entrance/exit and passage. For example, in the case of a device that controls entry and exit, an ID card league installed at the main exit will unlock the main exit only when an ID card with a pre-coded ID code is read. .

Furthermore, in recent years, so-called prepaid cards (prepaid cards) have been widely used. A prepaid card is a magnetic card on which the remaining usable power is written, and the device that accepts and processes this prepaid card has a means to rewrite the data as a new remaining power by subtracting the used power from the remaining power. LJ has been established.

Magnetic cards are generally used as recording media in devices that automatically manage the use of facilities and devices in this way.

(C1 Problems to be Solved by the Invention) However, with devices in which the ID code and remaining power are written by magnetic recording, there is a problem in that it takes time and effort to attach the card to a card reader/writer when using it.For example, When used for ski lift management at ski resorts, users usually wear gloves and carry ski poles, so it is extremely difficult to take out the card at the lift gate, attach it to the card reader, and then remove it. It was a time-consuming operation.

In addition, in the conventional magnetic cart, the cart' medium j1
11, it was not possible to confirm the contents of the data tα, and furthermore, it was impossible to write or read data from the outside.

The present invention was created in view of the above problems, and allows data communication to be performed with a device by simply attaching it directly to the body and approaching the device to be used. An object of the present invention is to provide a bracelet-type contact recording medium that allows data to be written and recorded contents to be confirmed from the outside.

(d) Means for Solving the Problems In order to achieve the above object, the present invention provides communication control means for transmitting and/or receiving data with an external device without contact, and a method for storing data. memory to

(e) Function According to the presslet type non-contact recording medium of the present invention, the memory continuously stores predetermined data, and the communication (a) control means communicates non-contact with an external device through an antenna or the like. The display section displays the contents stored in the memory, and the key input section is used to load or read data from the memory.All of this is done in a presslet-type case. A presslet-type non-contact recording medium is constructed as a whole.
