Specific embodiment
Whether voltage or temperature discoloring ink are combined together by the method for the present invention with electronic tag, by label
The state that is checked comes control voltage port or label temperature, so as to change the color of label surface color shifting ink, reaches mark
Know the purpose of tag state.While electronic tag completes interactive communication by electromagnetic field acquisition energy, by voltage-drop loading to electricity
Cause the color on the contact of off-color material, electrochromic material directly being changed by voltage-drop loading；Or changed by voltage x current
Become the temperature of label, change indirectly the color of electrochromic material.
A kind of electronic tag of the present invention, by chip, reinforcing wire, base material, antenna, conductive color shifting ink layer, film group of becoming attached to
Into；Described substrate surface sets gradually antenna under upper, become attached to film and color shifting ink layer；Described chip includes radio frequency mould
Intend front-end module, digital state machine module and storage module；Described rf analog front-end module is provided with port RF1；Described
Digital state machine module be provided with port V1, port V2 and port RF2；Port V1 and port V2 is by connecting line and discoloration oil
Layer of ink connects, and port RF1 and port RF2 is connected with two ports of antenna by connecting line；Described film of becoming attached to is arranged at day
Between line and color shifting ink layer；Antenna completes energy of electromagnetic field sensing, and rf analog front-end module realizes that signal energy is changed；Number
Word state machine module controls the flow direction of the state and inside tags data of label, according to the instruction for receiving, abstract factory
Changed between state, the content required for storing or returning；Memory module is used for storing user profile；When electronic tag is jumped
When going to the logic state or flag bit state specified, digital state machine control connects in port V1 and port V2 applied voltages
