How is the security of the Lunch-Check Card guaranteed?

There is a credit limit on the card of CHF 3,000. To speed up the payment process, the card works without a PIN code but is protected by a daily spending limit (default setting: CHF 100 per day), which the cardholder can change in the Lunch-Check app or in the customer center The Lunch-Check Card is issued and used subject to the General Terms and Conditions of Swiss Lunch-Check.
