The supported data-rates of the air-interface are one thing. The data-rate that you see after removing protocol overhead, waiting for eeprom writes and all the other stuff that takes time is a whole different story.

Long story short, the practical data-rate when reading from a tag or doing peer-to-peer transfers peaks around 2.5 kilobyte/second.

And depending on specific tags or the peer technology it can be a lot slower than that.
