Digital envelope system: a modern take 
My wife and I use a digital form of the envelope system. We call it a budget; we record how much we want to allocate each month to spend--for each category of expense--in a spread sheet. Why use prepaid cards? Why not open a bunch of bank accounts and use debit cards from each if you want to separate the money? You could also keep a ledger for each account that you spend from on a smart phone or even in a physical ledger.  The reason for the envelope method is that it psychologically hurts some people to physically part with cash. Once you digitize it in some factor, you lose what is the primary touted benefit, and it's no longer the envelope system. The secondary benefit that--once the budget for one category is gone, it's gone--is only as good as the discipline you have to not rob cash from another envelope; why is this any easier than the discipline of not debiting beyond the bottom of the ledger? So a budget IS a digital version of the envelope system; once the physical cash is removed from the equation, it's definitely not the envelope system. Sorry for the contrarian take on this question, but I've never been a fan of the envelope system for many of the reasons you have described. I guess I'm too young for the cash psychology to work for me.
