Near Field Communication Library
Near Field Communication (NFC) is a very short-range radio technology and is used for contactless communication between NFC-enabled devices and tags or cards. It has a range of typically no more than 4 cm, operates at 13.56 MHz, and supports transfer speeds of 106 Kbps, 212 Kbps, and 424 Kbps. NFC provides an easy and attractive means of communication as it allows devices to interact with each other merely by being moved to sufficiently close proximity.
NFC is a standard-based technology defined by the NFC Forum. A number of ISO standards are used in the NFC architecture, most notably ISO 14443 and ISO 7816 specifications. NFC technical specifications are well documented and available on the NFC Forum.
There are many use cases that the NFC service could support. Here are some examples:
- Smart Posters: Embed small electronic tags containing data such as a URL in posters. An NFC-enabled smartphone can read the data and act upon it if you hold the device close to the poster. The action taken when reading a tag can vary according to the type of data the tag contains and the nature of the application reading the tag. For example, the action can involve taking the user directly to a website that contains more information about the advertised event or product, or automatically sending an SMS message requesting that someone call the user.
- Ticketing: Gain access to theaters, events, trains, buses etc.
- Payment: Pay for goods or services using your NFC-enabled BlackBerry device similarly to how you use a credit card.
- Data exchange: Exchange data objects such as electronic business cards between BlackBerry devices just by tapping them together. Automatically configure devices by tapping them together.
The NFC library provides various APIs for creating powerful and engaging applications.
