How to implement node.js and RFID?

Question

Does anyone know how do I go about implementing this? http://www.youtube.com/watch?v=adF-H9mLuFs&feature=youtu.be

It will be great if anyone can provide me with step by step implementation.

Thanks in advance!

The RFID reader must have some kind of documentation for how you can use it.

There is probably a smarter way that you can link it to nodejs but one method would be to have the rfid reader write the data to a csv file and have nodejs watch that file via fs.watch. (See fs.watch in docs)

You would fire an event that reads the file each time it is written and then do whatever you like. You can update the browser using websockets. (See http://socket.io/)

This is probably not a great way to do it but it would work. Hope it helps! — John Steel, Jul 01 '13 at 21:43
