I have a payment card from cash app (which I never use but was given free money to get) that is glow in the dark! Took me about .003 seconds to realize in order for that card to actually glow in the dark it would have to be subjected to a light source for several minutes beforehand. Seeing as how I don't often keep a light in my wallet I have no idea what the hell they were thinking. There is no scenario in which I will ever pull out this card to pay for something and someone go "oh cool, it glows in the dark!" Unless I first say, "check this out... Just give me a minute here... Hang on... Ok, check it out, turn off the lights so I can pay."

I actually love this card for the conversation it provides. It's so stupid.

Can I see.the back as well?

What happens when the card no longer has any mongy left on it?

What's "mongy"?

Haha there was a time when Wells Fargo let you out custom images on your card and one format was a square in the corner that you can put your picture in. I uploaded a similar MS Paint smiley and they accepted it haha.

I think the best thing you could do with a custom card is make it look like something worthless like a gas station rewards card. If anyone picks it up or steals it there's a chance they won't examine it closer and try to use it as money.
