Your phone will ask you to allow installing from this site. That warning is Android doing its job — it appears for anything not installed from the Play Store.

1. Install ChargeLane and sign in with your mobile number.
2. Add credit to your wallet — it is prepaid, like a Beep card.
3. Tap Scan and point at this QR, or enter the code by hand.

Already have the app? Open it and scan this code again.
