Hi JavaRanch,
For experience, I would like to Develop this application. Is there a java library that can handle payment requests with something like a SUMUP AIR READER (Air Contactless Reader).
How secure can I make this?

Thanks for any advice.

I haven't used it, but it sounds like the Sumup app does it all for you. So maybe you don't need to do anything (assuming you're talking about accepting payments at the POS).

If you want to accept payment in your own app, you can integrate Paypal or Google Billing.

Thanks, That makes a lot more sense, till system with a separate payment system for cards.
Yes I want to build a till app you could use in a small business or yard sales etc. (POS)
