What is NFC
Near Field Communication (NFC) is a standards-based, short-range wireless connectivity technology that enables simple and safe two-way interactions among electronic devices. NFC technology allows consumers to perform contactless transactions, access digital content and connect devices with the simplicity of a single touch.
Implemented in mobile phones, the user can pay, get access, buy a ticket, request information or exchange contacts by touching a tag with his mobile phone (like the Nokia 6131 on the right)
Tags are small and inexpensive chips containing information. NFC defines the content of such tags to allow interopability between readers (like in mobile phones) and tags.
Service tags are NFC compatible tags (short NFC tags) allowing access to a Web site via storing a URL (also called „SmartPoster“ application) or allowing call back requests or SMS services via the NFC mobile phone. Service tags are supported as a standard feature by the Nokia NFC phone.
Furthermore NFC tags can carry application specific information. The content of these tags are handled by Java applications stored in the mobile phone.
