We have put the emphasis on security and have implemented 3 measures designed to increase protection on your account:
1. Passcode / Fingerprint authentication
When you register on your Yoyo-powered app, you will be asked to create a 4-digit passcode to protect your account. This triggers finger authentication if your device is equipped with this feature. Simply put, no one can access your account without your consent or knowledge -even if you lose your phone or if it is stolen.
2. Dynamically changing QR code
The QR code on the home screen of your app changes every 30 seconds when your phone is online (i.e. connected to WiFi or 3G/4G). When your device is offline, the QR code will change up to three times before it needs to be refreshed.
This means that if someone takes a picture of the QR code on your home screen they will not be able to use it as the QR code will have changed by the time they get to the till. 30 seconds is quite a short time!
3. Phone verification
Please refer to the section dedicated to phone verification for further information.
