Hi, I have a two part question that I'm hoping developers and users alike can help me with. For the Series 2 (S2 & Nike+) Apple Watch devices .... What do they use WiFi for? - I've noticed that transfering music from the phone onto the watch is at the same speeds allocated to Bluetooth 4 EDR but not WiFi. The same goes for workout app sync data etc. So what does the watch use for WiFi ... just WatchOS updates only? More importantly ... is the other wireless capabilities currently (aside from Bluetooth & WiFI). Can the Apple Watch S2 transmit wireless data at 12volts? Better yet can the watch suffice as a passcard for existing readers? The latter question, in bold, is what I'm mostly after and it's not easy to find out directly from sources such as JCI Inc (Johnson Controls Inc) world leader in Safety/Security access. Hoping someone has s definitive answer or can point me into the right direction. Thank you kindly.
