Zebra Technologies. They make the printers that print RFID tags. Check out it out at Zebra.com.
IMHO, it would be a good buy now that RFID is moving away from the early adopters into wide spread use.
The stock took a few hits recently as they did not have the kind of growth rate some investors were looking for.
To me it is more of an issue of how long it takes to roll out RFID integration projects.
I have owned the stock for years. It is a great company.
Good luck!
Zebra, got its start in BARCODES which were even more sinister than RFID - they were feared by some as the mark of the Beast. A zebra has stripes, and so do barcodes, thus the old company (which name I forget) re-branded to Zebra Tech.
I think you'll find Zebra is big in BARCODE printers, not RFID wafer or chip technologies.
