Problems solved by technology

However, since the portable electronic device is always carried by the user for use, this known sticking arrangement is likely to cause the RFID tag to be peeled off or its surface to be worn during the moving process.
Moreover, if the RFID tag is passive, the signal transmission distance is too short and the signal strength is weak; if the RFID tag is active, the attached power supply cannot support a long enough service life

Embodiment Construction

[0030] The present invention integrates the components of the traditional independent identification controller (i.e. RFID tag) into the circuit elements of the portable electronic device, such as in the embedded controller or the south bridge chip of the notebook computer or personal digital assistant (PDA), This avoids peeling off or surface wear of traditional RFID tags, and allows some components to be shared to save costs.

[0031] figure 1 It is a schematic diagram showing the first preferred embodiment of the present invention, wherein the identification controller is a passive tag, which must rely on the power converted from the induction signal transmitted by the reader to be driven.

[0032] Such as figure 1 As shown, the RFID system 100 includes a reader 102 , a first antenna 104 , a second antenna 106 and an identification controller 108 . The first antenna 104 is electrically connected to the reader 102 , and the reader 102 is used to generate a control signal a...

Abstract

This invention relates to a radio RF identification system including a reader, a first antenna, a second antenna and an identification controller, in which, the first antenna is connected with the reader generating control signals and transferring them via the first antenna, the second antenna receives the signals and the identification controller is integrated in the circuit elements of a portable electronic device and connected with the second antenna and selects a data signal based on the control signal to send it to the reader via the two antennas, which can avoid the traditional strip or wear of RFID labels to transmit signals even further.

Description

technical field [0001] The invention relates to a radio frequency identification system, in particular to a portable electronic device whose internal circuit elements integrate an identification controller. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology, which uses radio frequency signals to automatically identify targets and obtain relevant information. The operation is fast and convenient, and the identification action does not require manual intervention. Multiple tags can be recognized simultaneously. Radio frequency identification is an easy-to-manage, simple and practical technology that is especially suitable for automation control. It can be used in both read-only and read-write modes. Current radio frequency identification applications include: logistics and supply management, manufacturing and assembly, terminal baggage handling, mail and express delivery processing, file tracking and librar...
