RFID Deployment Problems

When working in environment with metal and liquid, what’s needed is not a high-power reader, but a low-power tag. A low-power tag requires less energy to wake up when interrogated by a reader.

For the dense reader problem, Generation 2 has modes where it anticipates dense reader deployments.

There is no interoperability testing going on for RFID. So, a dozen manufacturers can claim compliance with whatever the current standard is -- be it Class 0, Class 0+, Class 1 or Class 2 (Generation 2) -- but tags and readers from different manufacturers may not work together.

The world is heading to the Generation 2 standard, with products expected as early as the second quarter of 2005. Upgradable product path usually costly and not practical.
