RFID: Active Transponders + Reader (Long Range - 20-40m)

[Bobby Sardana]

Following are my requirements for an RFID application that I'm prototyping:

1) R/W Transponders (400-900 MHz, or 2.4 GHz) - for long range
operations (20-40m). Should allow 1K-2K worth of storage capacity. The
higher the read range, the better.

2) Readers that can work with transponders (1).

Any vendors, sample kits that meet the above requirements? One factor
that is important is the cost. Would appreciate any feedback.

Thank you.

Which of their technologies has your chip?
I.e., 123kHz short-range inductive? Long-range 433MHz UHF?

Cost? Are you kidding? Cheap RFIDs are made to go 1/10th that
distance.

I love to cook with wine. Sometimes I even put it in the food.

It was a transponder for pallets.

123KHz received by chip, then into a uP, then response via a 433MHz
module.
