Authorize.net: MasterCard and Discover are modifying their rules
- dminor 17y agoPretty big change -- we were surprised we hadn't heard of it before. MasterCard support is only required for certain merchant codes though, whereas Discover has it required for all.
- alanh 17y agoGood move for Discover, making it harder to support one of the least popular card types. Real smart business move.
