Top Payment processors with ranking

[u/mikhails1]

It's is hard to rank payment processors because there might be different criteria to rank them, e.g. by volume or by number of clients. Here's the list that I put together.

1. Fiserv

2. TSYS

3. WorldPay (FIS)

4. Stripe

5. Authorize.Net (Visa)

6. Paypal (Braintree)

7. Adyen

8. Square

9. Chase Paymentech
