How to implement RFID lift-n-learn widget

RFID reader can be used as a keyboard input.  We can create a hidden text input box in HTML5 and change the input content with the input from the RFID reader.

In our sample code, the playback content switches between images that corresponds to the input text from each RFID tag.

For deployment, administrators can use the RFID input as a query string to display information for corresponding items.
