Imagine a card which actually communicates with the holder by showing them information on loyalty points, promotions and membership details etc which can be updated every time the card is used, at the point of the card usage. A rewritable card is a very unique communication tool as the data is not only stored on the hidden magnetic stripe, but is human readable too. Rewritable cards can be updated with new text, graphics and barcodes over 500 times without the need for expensive ribbons, ink cartridges or other consumables.
