Feb 14, 2020 at 18:08 comment added jamesqf Not exactly a solution, but I'd suggest getting several other cards. Then you'd at least have one to pay for gas, and possibly could rotate the ones you use to avoid triggering fraud protection logic.
Feb 14, 2020 at 16:19 comment added dwizum @RonJohn technically, the network and the issuing bank are both involved in fraud detection. For instance, Mastercard stops some transactions on their own, but they also hand us a fraud score and we can choose a threshold within our system to stop additional transactions (and, of course, we calculate our own fraud score and use that too).
Feb 14, 2020 at 15:13 comment added ceejayoz Do you have a regular old consumer Mastercard, or a business oriented one? These sorts of volumes wouldn't faze a bank if it's on a business account.

Feb 14, 2020 at 15:01 comment added RonJohn Are you sure that the problem is Mastercard? Because with Visa, at least, it's the issuing banks that are responsible for fraud protection. I agree with @pboss3010 about getting a card from a different bank.
Feb 14, 2020 at 14:51 comment added pboss3010 Does this happen even after you continue to patronize the same vendor? Normally, fraud detection is about patterns. Otherwise, have you tried using a different card?
