Yes, you use the TWINT Prepaid app. To sync, open the TWINT Prepaid app, click on «Register», enter your contact details and take a photo of your ID. In the menu, go to «Top up credit», then «Bank account» and choose Hypothekarbank Lenzburg. You'll be asked to take a photo of your neon card and enter your IBAN. After verification, the bank will authorise the connection between neon and TWINT, which usually takes 1-2 working days. TWINT Prepaid is a prepaid service, so you'll have to move money from neon over to TWINT before you can start using TWINT to make payments – top-ups of up to 200 CHF are available immediately.
