Implementing RFID is a Business Decision, Not a Technology Question

Obfuscate Me with Facts

According to Merriam-Webster’s Dictionary, “obfuscate” means 1 a : darken, b : to make obscure, 2 : confuse.
And that is exactly what often happens in considering RFID.
You should, by now, be familiar with the benefits of RFID: non-contact, non-line-of-sight reading, read/write capability, etc.
The problem is that different RFID systems have different capabilities and costs.
Not all tags, for example, are read/write. Some tags are active, some are passive some are semi-passive. They don’t all have the same data capacity or range. Similarly, the different operating frequencies don’t offer the same range or data transfer rates. And not all frequencies are legal in all countries.
Nonetheless, we often find hopeful stories that conglomerate all the best features of every available system into an imaginary product that, in the words of Dr. David Allais, “does everything, costs nothing and fits on the head of a pin.”  (At the time, Dr. Allais was referring to bar codes, but the analogy is perhaps even more appropriate for RFID.)
