Labeling Credit Cards for Use...?

[Anonymous]

Surely there's an app for this now days, right? lol

Seems like a spend tracker built into an electronic wallet is needed, that prompts which card to use at checkout. If that could ever happen.

I usually only keep the main 4 categories with me, and know which one is which by the card design. As I phyisically cannot fit all of my cards into one wallet, even have a phone case with 3 slots for CCs. lol  If a card is needed that is outside of my current category, I just grab it from the SD.

Generally, I have a spreadsheet that has all my cards and rewards. I updated it weekly if necessary. Otherwise, I usually know where most of my spend goes so I usually know what card to select. It's pretty easy for me to pop it open prior to going to the store or even when I'm on the line in checkout. Takes less then a minute to see what card is best and then I use that.
