RFID (Identificación por radio frecuencia) Las etiquetas a prueba de manipulaciones son etiquetas especialmente diseñadas para prevenir o notificar cuando se detecta un intento de manipulación. Estas etiquetas generalmente contienen un chip RFID y una antena que emite una señal cuando la etiqueta se retira del objeto al que está unida o dañada. This technology is widely used in asset management, supply chain monitoring, anti-theft and security fields.
There are usually two working principles of tamper-proof tags:
Physical switch mechanism: When the tag is removed from the object it is attached to, a physical switch opens or closes, which changes the read signal of the RFID tag. The monitoring system can infer whether the tag has been illegally removed by reading the change in the signal.
Tamper-detection material: The tag may contain a special material that changes the circuit of the RFID chip once the tag is damaged, causing the signal to change.
En aplicaciones prácticas, RFID tamper-proof tags can be integrated with access control systems, alarm systems or other security systems to immediately sound an alarm when the tag is tampered. Por ejemplo, using these tags on library books, high-value goods or sensitive data devices can immediately notify administrators when unauthorized removal attempts are made.
