What's The Difference Between 1st Gen Wallet & 2nd Gen Wallet?
The differences between the 1st and the 2nd generation wallets are that the 2nd generation wallet, supports multi-currency, rather than only bitcoins. And we also switched from wireless charging to contact charging for better battery performance.
Most importantly, the S.E. Chipset on 2nd generation wallet (CoolWallet S) handles all algorithmic calculations instead of partial calculations to ensure maximum security.
