Alternative To QR Code Uses NFC and Cheap Rectennas

An anonymous reader writes "The BBC reports researchers in Korea have developed a technology that can be used as a viable alternative to QR codes. Made of plastic and electronic ink, the rectennas cost less than one penny each to produce and use the NFC standards for wireless radio communication to devices. They are seen as a cheap, easy-to-print and environmentally friendly way to overcome the limitations and inconvenience of QR codes, the usage of which has greatly increased in the last few years."

Quoth the 2nd link in TFS (I know, I'm relatively new here):

A rectenna is a rectifying antenna, a special type of antenna that is used to convert microwave energy into direct current electricity.

I'm assuming environmentally friendly vs metal/semiconductor antennas on existing NFC devices, not as compared to QR codes which are clearly very env. friendly.
