Where do I use RFID?

A generalization of another favorite question I get asked – “will RFID work in my application”.  The answer is usually a resounding yes. There are obviously situations where it doesn’t make sense, either practically or economically, to use RFID. Tagging low value items with a high cost single use tag is probably not a good idea. Using an RFID system in an application with large amounts of ferrous metal may pose a challenge. But in those situations where the tag is re-used the answer is almost always a big YES. Asset tracking, reusable containers, harsh environments, and non line-of-sight applications for example are classic candidates for an RFID system and you will find that initial cost issues will disappear when you look at the return on investment.
