Abstract

A contactless memory carrier for which it is not necessary to fabricate a barcode and a tag using separate processes is provided. The memory carrier includes a memory which stores data; a control circuit which reads the data from the memory in accordance with a signal transmitted contactlessly from an interrogator; a converter which converts the read data in accordance with an algorithm; an image signal generating circuit which uses the data converted by the converter to generate an image signal; and a display device which uses the image signal to display a code. The data converted in accordance with the algorithm may be stored in the memory in advance. In that case, it is not necessary to provide the converter for converting data in accordance with the algorithm.

Description

technical field [0001] The invention relates to a storage carrier for transmitting and receiving signals in a wireless manner. Background technique [0002] The technology (RFID: radio frequency identification, Radio frequency identification) that wirelessly transmits / receives signals to identify individuals is being put into practical use in various fields, and its market is expected to further expand as a new information communication method. In RFID, signals are mainly wirelessly transmitted / received between an interrogator called a reader, a reader writer, or an interrogation transponder and an RF tag. The RF tag stores identification information, and by wirelessly transmitting / receiving signals with the interrogator, the identification information stored in the RF tag can be read out in a non-contact manner to perform individual identification of the object. In many cases, the shape of the RF tag is a card shape or a chip shape smaller than a card, but various shapes c...
