We've seen about 70 percent read accuracy when scanning bar codes on bags traveling down a conveyor. With RFID, we are getting read rates of about 98 percent. We recently resolved the problem of having dead or quiet tags enter the system, so the read rates should get up to 99 percent.

This is something we are very excited about. People love it because they don't have to worry about checking their bags. They get through the airport more quickly, and they use the airport's slot machines more, so there's a benefit for us.
