How is that supposed to work? The toll free number on the back of my card just goes to some customer support line with 30+ minute wait times. There's absolutely no chance that a cashier is going through that for a typical transaction. Also, the whole point of this program is to make this less awkward for transgender people. Being deadnamed might be bad, but at least it's straightforward. The cardholder name matches the one on your government id, and the picture in the government id matches your face, done. I'm not sure how having mismatched names and having to call the bank is more pleasant.
