I have several vending machines and I want to be able to have the status of the machines in any specific time. The machine generates a dex file that could be read and that needs to be load to this application and from that point manage the number of products sold per machine, how much money should be in the machine, and manage the inventory inside of the same. Also I want to be able to know when the unit has alerts like when it is out of service or the door was open, or the unit is off, etc.
If you are interested, I would like to know what tools would you use, and how can we transfer the file from the machine to the web application for updates. This vending machines work with MDB Protocol.
