Proverbial Wallets

Financial sixth sense

We have trouble controlling our consumer impluses, and there's a gap between our decision and the consequences. When we pull a product off the shelf, do we know what our bank account balance is, or whether we're over budget for the month? Our existing senses are inadequate to warn us.

The Proverbial Wallet gives us that financial sense at the point of purchase by un-abstracting virtual assets. Tactile feedback reflecting your personal balances and transactions develops a subconscious financial sense that guides responsible decisions.

Peacock: The wallet appears to grow and shrink using a servo to reflect the balance in your accounts. Your assets will be on display to attract potential mates.

Mother Bear: The wallet protects the money within it when you need to be thrifty with a shorted motor in the hinge that resists opening. It promotes saving to weather out financial winters.

Bumblebee: The wallet buzzes through a vibrator motor whenever your bank processes a transaction. This encourages a conscious connection between handing over your credit card and your hard-earned money being harvested from the bank, and alerts you to fraud when you get a buzz without making a purchase.
