Interesting article from DigitalSignageToday.com about the potential shift from QR Code to NFC (near field communication) technology. [November 8, 2012]
“There is a huge opportunity to use NFC to engage customers,” said Daminani, who used the example of an NFC-enabled poster. The customer merely has to tap his phone on it to get the value, which is usually something like a coupon or a piece of information. This is a much easier way for them to engage than to go through the multistep process of scanning a QR code.
“It’s the most intuitive technology we’ve seen in years,” he said.”
