Contactless payments are not as widely accepted as in the UK so download the apps you know you’ll need and sign up before setting off to make the at-charger experience easier.
Usually Charge Point Operator apps work by linking a credit/debit card or PayPal account and then the chargers are activated by scanning a QR code.
Check the Zapmap app for information on the payment options available at your chosen charge point - details are available in the 'Info' tab of each charger on the map. Be mindful of the currency you’re paying in, and make a note of the conversion rate so that you have a clear understanding of how much you’re paying to charge.
