What Kind of Bandwidth does NFC Provide?

Question

I\'m looking into starting some projects with Android and NFC. What kind of bandwidth does NFC provide? This is assuming I had a suitable NFC reader/writer attached to an Ar

Answer 1

NFC supports 106/212/424 kbit/s. Apparently there are 848 kbit/s cards also, but they're not compliant with the standard.

That being said, the speed you'll get in the real world depends on the device/card you're using. It's not all that fast in reality.

Another reason for using bluetooth for the actual transfer is proximity. Bluetooth has a much better range than NFC. NFC's range is pitiful, simply put. For an NFC-only transfer, you'd have to make sure the devices were very close the entire time(and preferably not moving). For NFC hand-off to bluetooth, you just have to tap them for a half-second or so, and then it doesn't matter if they move around the room.

Now, if you're just talking about sending a few kilos here and there, it's not a problem.
