Periodically the M2 card reader will require an update in order for it to be used to complete checkout via the MassageBook Manager app. If you see a message that your card reader needs to be updated, you can apply this update by:
- Open the MassageBook Manager mobile app.
- Select the menu option in the top left corner of the screen.
- Select App Settings.
- Select Checkout.
- Select Hardware.
- Select Apply Update.
The reader should then begin updating and you should be able to track the progress of the update directly within the app.
Note: Your card reader will need to be charged at least 50% in order to apply the update.
