Non-hackable RFIDs
You might not realize it, but radio frequency identification (RFID) tech is everywhere these days. From the cards in your wallet, to inventory control in warehouses, it’s the technology that works behind the scenes to power the world around you. RFID has brought efficiency to complicated industries and makes our tiny devices and everyday carry items speak to each other. But RFID technology has also been very vulnerable to security attacks and information hackers – until now. A team of researchers from MIT and Texas Instruments have developed a new kind of RFID chip that they believe is impossible to hack.
The new RFID chip is made of ferroelectric crystals, which are material made up of molecules arranged in a lattice pattern across three dimensions. Thanks to this unique structure, when you apply electricity to the lattice, each cell can be polarized as either positive or negative, representing the values of a bit of information. Because the cells retain their polarization when the electric field is removed, the chips can store data even when they’re powered off. Texas Instruments developed a series of 3.3-volt capacitors for the chip’s energy source, and 1.5-volt cells for data storage.
