Thanks for the advice! I'm having some back and forth with them, and it does seem that I would need a new board for the setup. At the price points they're quoting, it is getting to the point where it's no longer a reasonable purchase. Thankfully, I hadn't finalized the deal, and they've got another buyer in line. I'll be taking a closer look at new models and customized features.
Hi there folks! I’m in the process of purchasing a custom build Innovative Vending Solutions unit. It was built to accept ONLY credit/debit only. Im looking forward to working with this machine, and fiddling around to determine a working configuration to add the bill validator and coin/change operations. It’ll be a headache, but as the unit is customized for office supplies and is otherwise precisely what I need for less than 4k, it’s a worth wild venture.
