In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are given in conjunction with the accompanying drawings, which are described in detail as follows.

Figure 1 is a block diagram of the system components of the present invention. In FIG. 1, the electronic tag system can be divided into a tag device 110 and a reading device 120. The tag device 110 includes a tag induction coil unit 130 and an encoding unit 140, and the reading device 120 includes an induction coil unit. 150. A thermal imaging unit 160 and an arithmetic processing unit 170.

First of all, during the inventory, when the reading device 120 is close to the tag device 110, the induction coil unit 150 of the reading device 120 and the tag induction coil unit 130 of the tag device 110 should be electromagnetism, magnetism and electricity due to electromagnetic effects. The thermal energy is generated to cause the encoding unit 140 to generate a thermally encoded image. At this time, the thermal imaging unit 160 of the reading device 120 is used to sense the thermally encoded image, and then through the arithmetic processing unit 170, according to the thermal imaging unit 160 The hot-coded image performs bar code and coded image analysis and image recognition to obtain the corresponding code to achieve the purpose of product coding and reading.
