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.

When do I start?
