I'm thus far voting on the CoolWallet overall. "Case" looked good but then I read about them using multi-sig and keeping 2/3 keys in their FAQ. I personally don't want the ability for them to "recover" my wallet although I suppose it's better for the everyday consumer.
Case is extremely secure because it is built on top of a multi-signature, multi-factor architecture with no single point of failure. Your bitcoin wallet has three keys and two of them are needed to complete a transaction. One key is embedded on the device so it is secured by the possession factor. No one can gain access to this key without having possession of the device. However, this key isnt enough to complete a transaction. A second key is stored on our servers and transactions are only signed by the server key if the fingerprint scan is a match so this key is secured by a biometric factor. That means even if your device is lost or our servers are compromised, your bitcoins are safe. A third key sits in an offline vault and is only used if you ever lose your Case to help your recover your bitcoins.
