Biosensor estimates for Blood Alcohol Content.
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.
01. Users link cards to the DrnkPay app (iOS and Android), then select the number of drinks they wish to have in advance (e.g. 3 pints of
beer)02. The types of payments to block are selected (e.g. bars / pubs, food, flights, online shopping or all categories).
03. All cards are then blocked for 12 hours.
04. A breathalyser, which is connected to the system via bluetooth, is used before each purchase to authorise payment.
05. If the user is under their pre-defined limit, the relevant cards are activated and payments can be made.
06. If the user is over their limit, their cards are blocked and cannot be used.
07. If your cards are all blocked, DrnkPay has a ‘Help me out feature’ allowing you to order an Uber home so you can get home safely.
