Mobile phone system based on radio frequency recognition principle

Abstract

The invention discloses a mobile phone system based on the principle of radio frequency identification, relating to the technology of input equipment of mobile phones. The mobile phone system of the invention comprises a second keyboard based on an electronic tag circuit and a mobile phone section, the second keyboard is not contacted with the mobile phone and sends data to the mobile phone in a radio frequency way. The mobile phone system of the invention utilizes the automatic identification function of a read-write module in the mobile phone to an electronic tag and the uniqueness of the unique coding of the electronic tag to integrate a plurality of the electronic tags into the keyboard to cause the unique coding of each electronic tag to be corresponded as a keyboard input signal. A key switch can be used for controlling whether the electronic tags operate. After a key is pressed, corresponding electronic tag information can be converted into the key input of the mobile phone, thereby realizing the quick input function of mobile phone information. The mobile phone system of the invention utilizes the characteristics of the radio frequency identification technology to realize the keyboard of the mobile phone with no power supply, fast connection and configuration and portability and can effectively increase the input speed, thereby solving the problem of inconvenient inputof the keyboard of the mobile phone.

Description

Mobile phone system based on the principle of radio frequency identification technical field The invention relates to the technical field of input devices, in particular to a mobile phone portable input keyboard and system, mainly a mobile phone system based on the principle of radio frequency identification. Background technique Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology based on the principle of radio frequency. The most basic radio frequency identification (RFID) system consists of the following parts: electronic tags, readers and readers host system. The working principle of the radio frequency identification (RFID) system is as follows: the reader scatters a radio frequency signal of a certain frequency through the transmitting antenna, and when the electronic tag enters the working area of ​​the transmitting antenna, it senses the radio frequency signal to generate an induced current, and extracts energy from...
