New App Stops You from Spending Money When You’re Drunk

DrnkPay is a smartphone app that stops users from making purchases while drunk. It blocks your credit cards for 12 hours if it thinks you’re too drunk to shop.

How does a smartphone app know when you’re drunk? DrnkPay is an app that connects your credit and debit cards to the BACTrack breathalyser or QuantacTally biosensor wearable so it knows how much you’ve drunk and limits certain purchases if you’ve had too much. Once it decides you’ve had too much to drink, it locks your credit cards for 12 hours. 

For DrnkPay to work, users have to link their credit/debit cards to the app. They can then set a limit of drinks they wish to have and the app will only block the cards if they go over it.
