I figured out how to stop theft at ATM ang POS remittances. Looking investor from patent , production and sale of the product. Even 1$ profit of man, it comes to many millions of people , who would buy such a product to protect them from possible theft of their DATA and save money .
If idea is that good, make bussiness plan and try to get offline iinvestors, as i see you will need few grands for that.
You need to make proper bussiness plan and present it to investors, if they see value in that, they will invest more likelly. Its how you make it and how you present, they just need to see potential in that
the idea is brilliant. And the business plan is ready. But without money to patent it is impossible not explain in detail. However I have to protect it from plagiarism theft
