(RFID) Small radio transponders or “tags” designed to be attached to items like products in a supermarket to allow the items to be identified and tracked by a remote system. Typically an RFID tag includes an integrated circuit that stores data and interfaces to the antenna, allowing the stored data to be retrieved by the remote system.
- Radio frequency interference
hardware, testing (RFI) Electromagnetic radiation which is emitted by electrical circuits carrying rapidly changing signals, as a by-product of their normal operation, and which causes unwanted signals (interference or noise) to be induced in other circuits. The most important means of reducing RFI are: use of bypass or “decoupling” capacitors on each active device (connected […]
