I briefly worked for a place that paid to a pre-paid Visa card like you're saying. They basically gave you the card when you started and you did all the activation. It was a temp agency so it made it more convenient when it came to getting paid per diem or for short term work. The business paid the agency, the agency paid you. At the time it didn't seem too sketchy (20+ years ago) but I'd be pretty cautious about doing something like that now.
