The Smartphone world is to take further steps into adding to its NFC (Near-Field Communication) additional strengths and capabilities and provide more options and new features to essential parts of our daily activity, such as unlock doors and cars (and locking?)
Near-field communication (NFC) is a set of communication protocols that enable two electronic devices, one of them being i.e. a smartphone, and to establish communication by bringing them within 4 cm (1.6 in) of each other. NFC devices are used in contactless payment systems, similar to those used in credit cards and electronic ticket smartcards and allow mobile payment to replace/supplement these systems.
NFC-equipped smartphones can be paired with NFC Tags or stickers that can be programmed by NFC apps. These programs can allow a change of phone settings, texting, app launching, or command execution.
Such apps do not rely on a company or manufacturer, but can be utilized immediately with an NFC-equipped smartphone and an NFC tag. There are standards and specifications determining how during the NF Communication tags can be identified.
It is said that Apple is to upgrade the software of iPhones which come with NFC chips and enable the unlocking door (hotel rooms, cars, office, home). More secured than Bluetooth technologies, NFC can serve as well to manage access to security areas at the time it storages its data in the chip itself rather than getting it aggregated to the operational system of the phone.
With better capacity and larger covered areas by NFC chips (a little bit more than “near”) this shall accelerate the IOT world expansion. Still, data and communication security is going to be always “The” main issue.
