I stumbled across a prepaid debit vendor called CUmoney that, as far as I can tell, services small regional credit unions only. Some specific details are hard to come by with this company.
According to this page https://www.cumoney.com/how-to-load-your-card/how-to-load-your-cumoney-everday-spend-card/
The CUMONEY® Visa® Everyday Spend Card can be reload with funds online, by debit or credit card.
If any forum members have this prepaid card can you answer this question. Does the debit or credit card we use to add funds to the CUMONEY® Visa® Everyday Spend Card have to be from the financial institution that issued the CUMONEY® Visa® Everyday Spend Card or can any credit or debit card be used?
