How much access do developers have to the NFC chips in iPhones and Apple Watch? I locked myself out of work again today. My multifunction smart card has NFC to open doors, and a chip which my laptop reads to connect to VPN. About 5 times a year, I leave the card in the laptop and leave the room, and then can't enter again without phoning the Helpdesk. If I've taken my phone with me. If there's a mobile signal. There has to be a better way! I've been looking at an NFC ring on Kickstarter, it's pretty cool. I could buy a USB read/writer, and copy the information on my smart card. I could then paste it into the ring, or onto a sticker on the back of my iPhone, but it seems pointless when it already has NFC - assuming it's possible to access it.
