Abstract

This invention relates to an RF induction system with interactive functions and an induction device for the same. The RF induction system has an induction device, an electronic device, a card reader and an application server, wherein the induction device is mounted on a carrier which has an electronic tag and a modulation module; a headset input interface (jack socket) connects between the electronic device and the modulation module connecting to an RF micro-controller of the electronic tag. When the electronic tag approaches to the card reader, digital information is processed and modulated to a audio signal via a headset output interface (jack plug) to be outputted to the electronic device which has the headset input interface (jack socket). When users use the electronic tag for induction, the electronic device interacts to the application server by a network for diversified applications.

Dependent claims

An RF induction system with interactive functions comprising:

an induction device comprising
a carrier;
an electronic tag mounted on the carrier and comprising
an encoder that stores digital information;
an antenna for receiving an electromagnetic radiation;
and
an RF micro-controller connected to the encoder and the antenna, wherein the RF micro-controller is driven to process the digital information in the encoder, converts the digital information to an RF signal and responses the RF signal via the antenna after the electromagnetic radiation is received by the antenna;
a modulation module that is mounted on the carrier and connected to the RF micro-controller of the electronic tag and modulates the digital information outputted from the RF micro-controller to a audio signal;
and
a headset output interface connected to the modulation module for outputting the audio signal;
an electronic device which is connectible to Internet and comprises
a headset input interface for connecting the headset output interface of the induction device;
and
a demodulation application which is corresponding to a modulation application of the modulation module for demodulating the audio signal outputted from the induction device to obtain the digital information;
a card reader emitting the electromagnetic radiation to drive the RF micro-controller of the electronic tag, receiving the RF signal of the induction device, processing the digital information of the RF signal, and outputting the digital information;
and
an application server connected to the card reader for receiving the digital information, and connected to the electronic device via the Internet for communicating with the electronic device.
