Touchcode is an interesting company that prints an invisible capacitive ink onto physical products (at this stage it looks like most of their examples are on paper). Printing this ink allows the item to be placed onto a smartphone screen and trigger a unique event.
This isn’t anything majorly new – Disney, amongst others, have used pretty much the same concept on their App Mates products. Still, it’s encouraging to see that more physical objects are being tied to their own digital presence.
I can see this technology being used in combination with NFC tags in stores as it essentially allows a similar outcome without the need for an NFC chip in the user’s device. A big barrier to entry, however, is that the user will have to be directed to a specific URL before touching the ink on the screen does anything.
