Buying and selling things with debit/credit cards

Assalamu alaykum! Sorry if there are mistakes, English is not my native! For two months I have been continuously trying to find fatwas on the Internet about whether it is permissible to sell goods online. The problem is that if you are a seller, in 90% of cases you will be paid with credit cards. As far as I understood, credit cards are strictly prohibited, even if paid before the interest is added. Also, all sheikhs forbided to take coupons, since this is also riba (I’m here talking about non-islamic banks). The problem is that when a customer makes a purchase with a credit card, the seller sends 1-3% of the commission to the bank, which serves the customer. That is, the buyer gives his money from the bank and comission is returned back to the same bank. These commissions (about 50% from 1-3%) always then goes for creating coupons for the customers. Thus, it turns out that the merchants help banks with creating riba coupons. And the question is, what should I do? Scholars didn’t prohibit to buy cars and fly on airplanes, even though we pay for insurance, cause of it’s ubiquitousness and inevitability. Still, I have doubts, cause I’ve couldn’t found any evidences. There are fatwas where it is allowed to accept credit cards, and they referred to the fact, that there is no difference for the seller with which money do customers buy their products. But no one of them didn’t take into account that very commission which sellers send to the issuing banks to create coupons. I’m in desperate. It is clearly a riba, but at the same time there is no other choice. I’ve just wanted to open an online store and for two months I’m just non-stop searching for non-existent fatwas.
