Evolution

Theanti-counterfeitingproductsonthemarketaredividedfromtheperspectiveoftechnicalfeaturesandfunctionalevolution,andcanberoughlydividedintofivegenerationsofproducts:

Thefirstgenerationofproducts:laserThelabelrepresentstheproduct.

Consumersdonothavetheabilitytoidentifytheauthenticityofthelabel,andthelabeliseasytoforge.Intheabsenceofcomparability,60%ofcounterfeitproductsand100%ofgenuineproductsaredifficulttoconfirm;followedbytemperaturechangelabels.Althoughconsumersareeasytoidentify,theyarealsoeasytoforge.Alsoevolvingatthesametimearenucleartrackanti-counterfeitingandsoon.

Second-generationproduct:Inquiry-typedigitalanti-counterfeitinglabel.

Consumerscanchecktheauthenticityofdigitallabelsthroughphonecalls,textmessages,andtheInternet.However,sinceanti-counterfeitingdigitalnumbersareonlyprintedonthesurfaceofpaper,theycaneasilybeforged.

Paper-grainanti-counterfeitingtechnology:Thepaper-grainanti-counterfeitingtechnologyisusedforanti-counterfeitingbyextractingandidentifyingtheanti-counterfeitingfeatures(ie,papertexture)naturallygeneratedbypaper.

• Highsecurity

Electronictagshaveareliablesecurityencryptionmechanism,becauseofthis,thesecond-generationresidentsofourcountryBothIDcardsandsubsequentbankcardsusethistechnology.

• Easytoverify
