Update: No, this is not the mark of the beast. Read my comments below.
Update: No, NFC-implants are not smart to use for identification/security purposes. They are not convenient and no real life NFC solutions are built around the concept of using only one chip for multiple purposes.
Update: Yes, there are relevant privacy and integrity concerns. Any technology implementation needs to give the user full control of all data and functionality relating to personal data such as location etc. Compare with your phone. It's a device that tracks every move you make using both cellular and GPS technology, it stores what write, you pass through everything you write through it, and through open networks... Of course, we need privacy/integrity protecting solutions in that context... as we would in an implant implementation. Those concerns are real and I understand the negative comments I am getting on those aspects. I just want to let you know, I feel the same way.
Update: This is just an experiment with no plans of actual public implementation. SAS has provided NFC tags to EuroBonus Gold members for a long time. The tag contains only the EuroBonus ID, in an encrypted format. Only SAS can write valid EuroBonus ID data to NFC tags. When traveling, you are always required to provide a valid ID when requested.
A few weeks ago I had an NFC chip implanted into my hand, just beneath the skin. In this video I use the chip to pass through Stockholm Arlanda airport, through security, at the lounge, and finally through the gate to the aircraft.
My NFC chip contains my Scandinavian Airlines EuroBonus member ID, and since the airport has NFC readers all the way from security to the gate, I can use the chip instead of ordinary boarding passes.
You will also meet Massimo Pascotto, working with innovation at SAS, and listen in on a conversation we had about the experiment.
At the end of the video, you can see how the actual procedure went. Viewer discretion is advised.
