As long as you have done your due diligence, in making sure your IP (intellectual property), is not already in the public domain then you can easily obtain investors. However, investors will not invest if it's just an idea, they need an actual working physical prototype to be able to understand what the idea is about. From reading your business idea, that idea exists in Europe, however it's called a loyalty scheme programme and aren't usually scalable unless you're able to partner with say Amazon or other retailers. Otherwise create a Kickstarter and you could easily raise the amount.
