Whale,
The whole
vending industry uses the MDB communications system to run the bill validator,
changer, and
credit card devices to vend a product. Coke and Pepsi pushed the MDB system so they could use any brand name for the devices that run the vendor; Coke and Pepsi got what they wanted.
The car wash industry runs on a simple pulse system that has been in place for years; MDB and Pulse do not talk to each other easily. There has to be an written interface between MDB and Pulse for them to communicate with each other. That interface has yet to be written by CryptoPay so that it will work on the MDB sytem used by ShurVend. The engineering time and cost to do this is what has kept CryptoPay from doing it because the market for this device is not very big. Remember ROI??
I'm not an electronics guy so I have to depend on others that are. I have enough trouble just keeping these new technologies running correctly. Electronics are wonderful when they work, but a pain in the butt when they don't!!! As fast as technology changes these days, it is a constant struggle to keep up!
