¹ Detailed rules for the use of Cashback can be found here.
² The accumulated cashback is credited to your card account once a year, provided the account has not been canceled at this point. If the card relationship has been terminated during the current card year, you are no longer entitled to receive cashback. Cashback cannot be paid out in cash. 
³ Except for fees, interest, back-charges, cash withdrawals, payments for bank transfers and currency exchanges (also into monetary surrogates such as cryptocurrencies, Travelers Cheques, topping up cashless payment methods etc.) as well as payments to securities brokers, payments for services associated with the card (e.g. optional insurance) and any gaming or similar gambling transactions.
⁴ In the first 3 months after issuing the cards, the cashback is 5%, up to CHF 100 at the most, with the Cashback American Express® credit card. This only applies to new clients (principal cardholders) of a Cashback Cards card duo (not including existing customers of a Cashback Cards card duo and a Cashback World Mastercard® or Cashback Visa individual card). Only possible once per person.
⁵ The use of the installment facility is subject to interest and requires both a credit agreement as well as a positive outcome from the legally required credit assessment. The detailed conditions are provided in the application. The issuing of credit is not permitted, if it may lead to excessive debt.
