NFC wins in this survey, but what about NFC in iPhones?
“It is about convenience,” Dodge explained. “One of the big things is not having to launch an app to use NFC. If we think about the Bluetooth beacon aspect, one of the biggest issues for the participants in the study was the fact that the information was pushed to them, which essentially took away their control.”
True that, but it depends on how you implement the beacon solution. CliqTags Spotter is more about providing a palette of information that the user can choose from, rather than forced notifications.
CliqTags supports beacons, NFC, QR Codes, SMS, e-mail etc. Please read the FAQs for pros and cons.
