Usb-a (or -c), and NFC will be available. Price for NFC should be around $30-35, to be confirmed. Plus various Kickstarter discount. We won't have bluetooth, at least in the first iteration. The chip we chose is pin-compatible with another one with BLE, so it's not excluded in the future. Honestly, I really hope Apple will announce a more open NFC next week.
