What is a tamper-evident RFID tag?

1. What is a tamper-evident RFID tag?

Tamper-evident RFID tags are a special design that offers greater security and tamper-proof protection. Such tags are usually used in situations where identification, tracking, and protection of targets are required, such as the management of high-value items and cargo identification and verification.

2. Design principles of tamper-evident RFID tags

Physical damage detection: This kind of tamper-evident RFID tag usually contains a physical damage detection mechanism. Destined tags usually use the method of installing an activation button. When the installation is completed, the button is triggered and the tag is activated; when the tag is maliciously removed, the button will be released and the tag activation information will automatically become invalid.

Edgeless tags usually use flexible and fragile materials to print the tag antenna. When the tag is removed, the antenna will be damaged and the tag will become invalid.

Encryption and Authentication Features: This tamper-evident RFID tag uses encryption and authentication technology to protect the security of data. These tags will perform authentication or communication encryption when communicating with readers to ensure that only authorized readers can access the information in the tags.

Anti-tampering features: This tamper-evident RFID tag contains some anti-tampering features such as an irreversible serial number or digital signature. These features make the tag’s information more difficult to tamper with, thus improving the tag’s security.

3. Application fields of anti-tamper RFID tags

Logistics Management: For the transportation and delivery process of goods.

Asset Management: Used to inventory and track company assets to prevent loss or theft.

Anti-counterfeiting and anti-counterfeiting: Used to attach tamper-evident RFID tags to product packaging or labels to verify the authenticity and origin of the product and prevent the product from being tampered with or counterfeited.

In the field of energy filling that our company is engaged in, unlike the IC card binding of people and cards, anti-tamper RFID tags are mainly used for vehicle card binding, which is a good solution for group fleet management; it can ensure that group vehicles are in Under effective supervision, drivers are prevented from using IC cards to make illegal payments to non-group vehicles.

4. Summary

Tamper-evident RFID tags use design principles such as physical damage detection, encryption authentication, and anti-tampering features so that such tags can provide effective solutions for item tracking, identity verification, etc.
