As someone who's been actively involved in engineering Bluetooth LE devices, believe me, with constant daily usage, it will NOT last 2 years. There are so many factors involved with BLE, not just limited to usage, but with respect to range, environmental conditions, etc. What's your point? None I actually forgot to add something to my original critique: if your device (iPhone) dies, and Coin isn't authenticated you can't use your card(s)!! Haha Can't believe I missed this. There's another bullet of flaws to add. Their FAQ is vague and doesn't really answer any questions, especially the important ones. They attempt to give clever and confronting responses to serious questions and most people can see right through that. Comments on their FAQ like "Should last" and "a lot can happen between now and Summer 2014" - get out here. If you want customers to pay (a premium) for an experimental product - be concrete and firm.

>Comments on their FAQ like "Should last" They quite clearly state the usage pattern for the 2 year figure. From said FAQ site (https://onlycoin.com/support/faq/ https://onlycoin.com/support/faq/) Q. How do you figure that a Coin will last 2 years? What constitutes normal usage? A. Here’s how we modeled typical usage. On a daily basis, we assume you’ll toggle which card you want to use and swipe your Coin 10-20 times a day. In addition, you may adjust which cards you want to store on your Coin a few times a week. Initially when you’re getting to know your Coin you will likely be syncing often. Over time we find that most people sync much less frequently once his or her cards are on a Coin. If you swipe and sync more frequently on a consistent basis, your Coin’s battery will drain more quickly.
