There are badge companies that offer these instead of barcodes. Last we looked at it there were 2 concerns, the first is that the badge price went from cents to dollars. The second was privacy. While I'm sure the price has come down in the last 7 years, I dont expect the privacy concerns have changed.

It would likely get expensive fast & privacy is thrown out the window but having small RFIDs in the badges would work too :)
