Frequently asked questions
What is Karto?
Karto is a digital loyalty service for businesses. Your customers get a loyalty card they add to Apple Wallet or Google Wallet, without installing an app. You track their visits and rewards from your merchant dashboard.
How do I add my loyalty card to my phone?
Scan the QR code shown by the business, enter your details, then tap "Add to Apple Wallet" or "Add to Google Wallet". The card appears in your Wallet straight away.
Do I need to install an app?
No. The card lives in your phone's Wallet. There's no Karto app to download, neither for customers nor, necessarily, for merchants.
Is Karto available outside France?
Yes. Wallet cards work on any iPhone or Android phone, wherever you are. Prices are shown in euros, or in Swiss francs for businesses in Switzerland. The merchant dashboard is currently in French, and we'll help you get set up.
How is my personal data protected?
Your data is processed in line with the GDPR and hosted in the European Union. You can access, correct or delete your data at any time. See our privacy policy (in French).
How do I unsubscribe or delete my data?
Email us at support@karto.cards from the address linked to your card: we delete your account and your data as soon as possible, and within 30 days at the latest.
I'm a business owner. How do I start using Karto?
Email us at support@karto.cards: we set up your loyalty card, your points or stamps mechanic and your merchant dashboard with you.
