*NEW DATA POINTS*
I'm sure some of you already know these points, but wanted to help those that seem to be having issues. AccountNow allows you to load up to $1500 per day from Reloadit Safe. Their "day" is a rolling 24 hours, which may be why so many people are getting the "invalid card" response when trying to load from safe. Here's what I did:
1. loaded funds into reloadit safe
2. loaded my card (onto Accountnow) for $1500
I had previously been trying to load more than that, which is when I got the invalid card error.
Hope this helps.
