Could you expand more on this I didn’t realize card networks actually got itemized data (e.g. $12.35 at the gas station was for a pack of cigarettes or some windshield wiper fluid and and some beef jerky)
The Level 3 data isn't sent from all merchants, but I have a feeling that larger ones pass along the info.
I also was incorrect above, only Mastercard and Visa support level 3 data. However, level 2 data is widely supported and can contain some purchase info (Clover lists the SKU of an item for example).
