Near Field Communication

bhaazee

It googled a bit about NFC (Near Field Communication) technology.

As a basic, the technology consists of a NFC chip with prestored data in it and a NFC receiver that receives data from the chips.

this means is it not possible to use NFC to transmit or receive data that varies with time (say weather). Since NFC involves transmission through short range radio frequency why is it not not possible to transmit and receive data that varies with time using short range radio frequency.

Also in payments with NFC technology, you place your NFC device near the machine that reads your data. Here in this case both the transmitter and receiver sends and receives varying data (various amounts, various card details). If I am not true with this case then whats the actual algorithm behind these hardwares

If such a technology exists could anyone share with me some links.

Thnx.

It is possible; but the economics and sensibility of continuously transmitting real-time data using NFC depends on whether or not there are devices in range to receive it. Most of the time there aren't or the range is too short, so it doesn't happen. There's no reason why a transmitter and receiver within operational range of each other couldn't continuously transmit/receive real-time data.

There are many- Most proprietary, some open source. You'll have to be more specific.

Smart Poster

Near Field Communication is limited to close proximity approximately 4cm. The NFC tags are both readable and writable so the information sent to the device (NFC Smart Phone) can be changed whenever required. NFC Smart Posters will facilitate connections when and where the consumer requires them. Unlike previous technology the consumer decides when to interact with a brand or organisation, it makes marketing far less intrusive.
