Smart Tamper Detection for the Physical WorldAs counterfeiting, theft, and unauthorized access become more common, businesses need a simple way to know whether a product, package, or asset has been opened or tampered with. This is where Tag Tamper) NFC technology becomes valuable.Unlike traditional NFC tags that stop working once damaged, the Tamper Tags continues to function after tampering and can return a different response or URL indicating that a seal has been broken. How Tamper Tags WorksThe chip contains an additional tamper detection loop separate from the NFC antenna. When the seal is broken, twisted, peeled, or cut, the chip permanently records the event and changes its response during future scans. The tag remains readable, allowing applications to display:"Authentic and unopened""Package opened""Seal broken""Product verification failed"This allows real-time verification using any NFC-enabled smartphone including Android devices and modern iPhones.
