Me and my brother planned a talk on Permanent Beta Day, but I also ended up being chipped with an NFC tag in my hand that I can program with almost anything. I won't need a key to unlock my door for example, or I can use it to share this site + contact details (this is the current setup). I'm probably gonna get a read/write setup for an Arduino that I can plug/connect to basically anything, and connect it up around my house.
Just a good note; It was done by a professional. Don't try this at home. These things can be harmful and they are experimental for a reason.
