Tamperproof ear tags offer the most security in livestock identification and management.
They are ideal for Official Registration and Certification Programs, as well as Official ID markets like Fairs and Shows because the male button is locked into the female tag making these tags "tamper" proof and unable to be altered. The button tip locks into the female and if stem is cut a new button cannot be put into the female tag.
Tamperproof tags are permanent and cannot be reapplied with a new button.
NON-Tamperproof tags allow you to use a new Male Button to reapply a female tag.
