Dual Frequency RFID Label

General purpose Tamper-Proof Dual-Frequency label

SIVA’s Duo-Fre 6326 TP is a general-purpose dual-frequency RFID label that is tamper-proof in nature, ideal for usage in applications where the user needs to ensure product authenticity and security. This label is non-transferrable and hence cannot be re-used once removed or tampered with.

The tamper-proof properties of the label are tested for various non-metallic surfaces including glass, paper, plastic, etc. and work extremely well. The antenna of the label will break if the label is taken off the surface or even on slight tampering. Once the antenna is damaged, the label becomes non functional and can no longer be read, thus proving an attempt to tamper.

The Duo-Fre 6326 TP is delivered with an EM4423 dual-frequency chip that can be encoded as per customer specifications. Printing of logos, text and variable data is also offered as an option to our customers.
