Lasu: your wallet’s early warning system

Lasu is a card in your wallet. It’s also an app on your phone. They work as a team to help prevent your wallet ever being lost. Here’s how:
Linked by Bluetooth: your Lasu card links to your phone using Bluetooth. Once connected, the ultra-thin card sits comfortably in your wallet
Alerts to your phone: if you accidentally leave your wallet somewhere, you receive an alert and last known location on your phone
Card cancellation: should your wallet go missing, Lasu can help out with card cancellations and replacements
Phone battery friendly: Lasu uses Bluetooth Low Energy, so you don’t need to worry about it affecting your phone’s battery life
No unwanted alerts: by setting zones where your wallet isn’t at risk – such as your home and workplace – you won’t receive unwanted alerts.
Compatibility

LASU works on the iPhone 4S and later running iOS8+
