Invisible inks identify fake products from your phone

Scientists in the US have developed sophisticated fluorescent inks which they believe could be used by consumers to spot a fake product just by taking a photo on their smartphone.

Researchers at Northwestern University have come up with inks, which can be printed using an inkjet printer, and are invisible under normal light. However, they can be seen under ultraviolet light and could be stamped as barcodes or QR codes “on anything from banknotes and bottles of whisky to luxury handbags and expensive cosmetics, providing proof of authenticity”.
