With NFC, there’s no such thing as a normal T-Shirt.
A T-Shirt can tell you as much about the product as it does the about person wearing it.
It can detail where and when it was made, what materials were used and of course how best to maintain the shirt to maximize its lifespan. All these questions can be easily accessed and answered by scanning the colored button with an NFC enabled smartphone.
Of course, this technology can also be used for other purposes.
