Smart Posters are signs, billboards, or any other form of advertising which allow you to reach your target audience through the novelty of modern technology. By incorporating a passive NFC (Near Field Communication) Tag, a user can extract data by touching it with their NFC-enabled handset (as is illustrated in the picture below). The data can be anything from simple text up to video and audio content.
What is NFC? NFC, short for Near Field Communication, is a short range wireless RFID (Radio Frequency Identification) technology that makes use of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth. It is meant for applications where a physical touch, or close to it, is required in order to maintain security.
RFID tags are placed on the common object, allowing the phone to interact with the object e.g. a poster. The tags contain a unique ID and up to 4 Kbytes of password protected memory (roughly equivalent to 4 pages of text); the content is encrypted for safe data storage. This is a market standard, proven technology, and the same type of contactless card used by the London Underground (the Oyster card ) and by the University of Wolverhampton staff for access control. The tags can be small (typically 1 square inch) and they are very cheap (less than £1). They are supplied in various formats, including in form of a sticker which can be attached to common object, allowing the phone to interact with the object.
