How many times have you wanted to buy a snack or drink from a vending machine, but had no cash? Right now, more than 40% of consumers now go at least a week without using cash! This means that vending operators and consumers are missing out big time and sales will only continue to decline at machines that only accept cash (which is most of the 5 million machines in the US). In fact, vending sales are down significantly compared with recent years. I've come up with an iPhone-compatible solution that is perfect for consumers to use, including teens and kids without credit/debit cards, and is easy for operators to deploy using their existing machines. I need an engineer to help build the prototype hardware and an iOS developer to compile the consumer-facing smartphone application. The potential to disrupt this multi-billion dollar industry is huge!
