    Geo RTD links NFC to sat nav and mapping apps

    The new tag data format will allow NFC phone users to access location-based information without having to go online.

    NEAR FIELD SOLUTIONS: Making Geo RTD specification freely available

    NFC specialist Near Field Solutions has introduced a new NFC tag data format designed specifically to carry location information.

    Geo RTD is based on the NFC Forum‘s Record Type Definition (RTD) specification and uses the ‘external’ namespace. This was introduced by the NFC Forum as a way for organisations to define useful record formats without the need to go through a lengthy standardisation procedure, the company explains.

    Geo RTD allows companies deploying smart posters to encode location information in a tag in a way that allows the act of reading it to launch an NFC phone’s mapping or satellite navigation software. This will allow the user to instantly see the location of a place of interest — such as a museum, art gallery or concert hall — and plan a route to the destination from their current location if they have GPS.

    ANDROID APP: NFCGeo supports the Geo RTD

    Smart poster applications that link to services such as Google Maps and Multimap using a standard web URL already exist, Near Field Solutions’ Glenn Needham explains. But “using a URL relies on the user having data connectivity enabled on their phone. This, he added, “is fine in your home country but when you are travelling in a foreign country you do not want to incur high data roaming charges simply to find the location of a tourist attraction.”

    Using sat nav software already on a phone, rather than requiring the user to go online, makes it more likely that a user will be able to see the desired destination on a map and plan a route to it without having to use online data, Needham adds.

    “Near Field Solutions have agreed to make the specification for this new RTD freely available so that mobile OEMs and NFC applications companies can use it across many devices providing interoperability and a consistent user experience,” says the company.

    A copy of the specification is available on request from Near Field Solutions. An NFCGeo Android app supporting the new RTD is also available from Android Market free of charge.
