Hi, This is Shota in UMS LLc. I'd like you to make wireless sales collecting system for japanese vending machine. I already has wired sales data printer.(please check the attached images.) I need you to build up wireless sales data collecting system based on the protocol on the wired sales data printer. As I have only 50 units of vending machines now, I have a plan to build them up with Arduino. If you have much better idea to make it cheaper and more simple, I'll choose your solution,not only Arduino. Please send inquiry first, then I'll give you detailed information. Thanks

Hi Shota, I'm interested in your project and want to discuss with you Some old sales data printer use RS232 standard as wire protocal. I also have experience in POS machine, i have made new product of POS working by wireless and bluetooth instead RS232 standard from old POS. That product also have bill printing and security lock and control by iPad or Android device. Honest arduino is simplest solution, but if you want to make something professional, i can make PCB with MCU in PCB, it will smaller and more suitable with sales data printer. Also can attach to data printer what you have sent in attachment. Wireless you can choose is bluetooth or standard wifi. I also can make housing from CNC or 3D printer to package them together Please contact me for more details I'm a leader, i have team with electronic engineer, mechanical engineer, plastic/painting/simulation expert, i also have workshop for electronic and mechanical, my jobs is build prototype from idea. Best regards

I would prefer ESP32 microcontroller with LORA data comunication. For the sales data printer i need the model-number. But I guess it will be a serial printer with Japanese ASCII Code. I don't understand what all have to be included. Only the connection to the printers, or POS incl. creditcards or coins... Please make more concrete, what you need.
