Are There Any Passive RFID Tags for Tracking Electronic Equipment?
Could the technology monitor computer motherboards? And could it be non-conductive and operate in environments with temperatures greater than 50 degrees?
Yes. Murata's Magicstrap is designed specifically for this type of application (see New Component to Simplify RFID Tag Production). You can meet representatives from Murata at this year's RFID Journal LIVE! conference and exhibition, being held in Orlando, Fla., on Apr. 8-10.
In addition, both NXP Semiconductors and Impinj have introduced RFID transponders for consumer electronics that can be embedded in a device's printed circuit board (PCB). Each chip has an I2C serial bus that links to a microcontroller or central processing unit via a wired connection. This enables new applications, such as the ability to lock a device after it has been manufactured. To unlock the device, a retailer would transmit a command to the transponder, which would then pass the unlocking code on to the CPU. NXP and Impinj will both be exhibiting at LIVE! as well.
