Can RFID Be Made Tamper Proof?
With RFID chips being used to track more products through the supply chain, it's a critical assumption that the chips are still adorning the products they were programmed to adorn. A company called Mikoh is selling devices to make RFID chips more tamper rWith so many retailers and manufacturers embracing RFID tracking throughout the supply chain, there is a strong assumption that an RFID label is still connected to the product it is supposed to be connected with. One vendorMikohis trying to challenge that assumption. Todays barcode is relatively easy to replicate and fake with an ordinary laptop, a small scanner and a low-cost inkjet printer. RFID labels are much more difficult to copy but, fortunately for would-be thieves, they are usually quite easy to remove and reaffix to something else. "There is no physical security in them at all. Its very easy to move the tags from item to item," said Peter Atherton, Mikohs Chief Technology Officer. "If you look at the benefits that RFID has to offer, those benefits are always greatest when RFID systems are automated to the maximum possible extent."
What Mikoh has created is a supposedly tamper-resistant sealdubbed Smart & Securethat would alert monitoring systems when a tag has been moved or changed. The system has two modes: a lower-cost option that will cause the chip to "stop working altogether"; a higher-cost approach where the chip will proactively alert monitoring systems that its been tampered with.
