In essence, it’s the answer to Google Wallet’s question of “How can we get real people to use this?”. It’s also the answer to many Costanza wallets.
Google Wallet’s goal was to thin down wallets and keychains by digitizing as many cards as you can into a mobile application. This is also Coin’s goal. When you combine the two, you’ll have the best of both worlds – all of the cards you can’t have in Wallet, you can toss onto your Coin.

Yes, Google is planning something similar. This, however, will allow you to use more than just a debit card, but all your credit cards, and even some you may not feel comfortable leaving in Google’s hands (If I am wrong about how Google Wallet already works, please, let me know as I have not used it in-depth).
Coin would also help widen Apple’s Passbook app. However, with the way we’ve seen Apple operate the technology would most likely be exclusive to the iOS platform. But a chamfered card would certainly feel nice.
