NFC standart: Why Apple does not like it?



As you know Apple does not support NFC. Also Apple does not like NFC and promotes iBeacons, based on Bluetooth LE.

There are some reasons for this. NFC has a number of disadvantages:


  • Another radio? No way Smartphones have to accommodate a number of radios. An iPhone5 must include radios for LTE (or GSM), WIFI and Bluetooth.

  • Serial interaction. NFC works well in a one-to-one interaction. But what happens when 10 smartphones want to interact with an NFC tag? the tenth will have to wait until the first nine have had a go.


Bluetooth LE does not have this limitations, but it also have some disadvantages over NFC: is more expensive and the server part has shorter battery life. But overall Bluetooth LE is in a better position to prevail in the battle for short-range peer-to-peer transactions.
