The situation

You parked at a supermarket and there is a charger that might be free or discounted. The screen is showing a QR code, a list of networks, or a message you are not sure about. You have maybe 30 minutes while you shop and you do not want to spend 10 of them figuring out the charger. You also do not want to accidentally sign up for a subscription.

How the scanner helps

Scan the screen and the scanner tells you exactly what is needed to start. Is it free? Does it need an app? Can you just tap your bank card? How much power will it deliver in your 30-minute shop? You start charging quickly and get back to your shopping list.

What to do

  1. 1

    Scan the charger screen in the supermarket parking lot

  2. 2

    Check the payment requirement: free, app-based, or contactless

  3. 3

    Note the charging speed to estimate how much range you will add during your shop

  4. 4

    Start the session and head inside
