Description

  The present invention relates to an electronic device, an information transmission method, and an information reading method, and more particularly to an electronic device, an information transmission method, and an information reading method that transmit or read encoded information.

A technique using a two-dimensional bar code such as a Q Response code (Quick Response Code, QR Code _™ ) as an information transmission medium has long been used.

  Compared to conventional one-dimensional barcodes, two-dimensional barcodes encode information in a two-dimensional image, usually represented by a square, black and white, two-color graphic, which allows for more data in a relatively high dimension. Can be remembered. In the current technology, data is stored using four types of standardized encoding modes of numerals, alphanumeric characters, binary data, and kanji in encoding of a two-dimensional barcode. These encoding modes can be quickly decoded only by an application program of a mobile phone or other electronic device, and information included in these encoding modes can be obtained. In this way, with the current development of 2D barcode technology, it is possible to omit a large amount of information retrieval process simply by applying an application program to the 2D barcode and decoding it. In consideration of convenience, the 2D barcode is not designed to be encrypted. In other words, if the electronic device is provided with decoding software related to a two-dimensional barcode, it is possible to decode the square image including the two-dimensional barcode and obtain the information.
