This smart wallet is one that is capable of protesting when too much cash is being shelled out.
The wallet is connected to 'Zaim,' a bookkeeping app that helps to monitor spending habits. The 'Living Wallet' has two modes: "save mode" and "consume mode." When a user's account has a negative balance, the wallet automatically uses its tiny wheels to inch away like a caterpillar to escape the grasp of those who try to grab it. It is even capable of turning around to make it even more evasive. But even when you manage to catch this feisty runaway wallet, it audibly emits cries for help.
Even if the wallet's cries do not deter a user from spending money, its last move is to call the wallet owner's parents for backup.
