Since its introduction in the iPhone 6 and 6 Plus, Apple has jealously guarded the access to the NFC chip that incorporates all its terminals.
The company only enabled one use of this chip: the contactless payment of the Apple Pay service launched at the same time. The developers were left out and could not integrate it into their apps.
This situation will change with iOS 11. Because Apple has made available to developers a new development framework called “Core NFC”. What uses can we expect from it?
Label detection and data reading
When using Core NFC, you can read NFC tags of type 1 through 5 that contain data in the NFC (NFC Data Exchange Format) format.
This is the summary of the NFC tag reading functionality, the full details of which can be found in the documentation provided by Apple on its developer site.
This translates into very broad uses intended to provide information to the user related to a particular location. According to the specifications of this technology, it has several advantages over Bluetooth LE:
- It does not require electricity or batteries.
- Limited to 20cm away, to avoid unintentional scans.
- Binds with the device in 0.1 seconds.
- Cost $ 0.10 compared to $ 5 that costs a label with Bluetooth LE.
This makes it the perfect candidate to provide information about a specific painting in a museum, a product on a supermarket shelf or pharmacy, to obtain a map of a shopping center, opening security doors in offices or hotels and many others Uses that are yet to be seen.
The strange thing is that Apple has fought a battle with the Australian banks for the access to the chip NFC and with this change, it is not clear if now they will be able to use it or the mobile payments will be excluded.
The catch is that this technology is only found in the iPhone 7 and 7 Plus, we do not know if the rest of NFC chips of other generations are able to read NDEF tags. In any case, with the passage of the years will end up extending as Apple launches new
