My thread may not be suitable for this section but I just want to fire away my question in case I can get some help. I have an idea on how to make secure transactions and reduce credit card frauds. My idea can be used in wide range of applications. Brokers can use it to reduce account frauds, credit card companies can use it to reduce account frauds and identity thefts. I want to talk to a credible agent or a financial institution and sell my idea. Anyone knows what is the best way to approach it and get a good money on that if I can convince that my idea is worth of implementing?
Put the idea into a thing, and then sell the thing. The two most common approaches are (1) thing = a US Patent; (2) thing = a company. In practice, buyers prefer to License a patent or buy a company, rather than "buy an idea". Now that you know what buyers want, don't argue with your customer. Be smart, sell em what they want.
