My recall wasn't entirely accurate & I was too lazy to go and look up the details for the OP. FWIW...I attempted to use a card called "vanilla visa", purchased and loaded with cash at Walgreens, when I got VIP. I too have read some posts where members said they were successful in using a pre-paid card (shrug)
The trustcash method was simple as could be. I took the number TER gave me, along with my money, to a Wells Fargo and handed them over. Done. The bank didn't need or want the form TER had me download and take to the bank. All bank needed was money and the number from TER. I assume the number somehow identifies the account the money is deposited into.
Thanks again for giving the OP more details. Regards.......RR
