wireless contact points

Other Hardware Product Design

Hi Folks,

this is a bit random, I am looking into using an "off the shelf" wireless payment reader. the strange part is that i need three contact points linking to the reader, and of course with different values.
I have contacted a few providers with little help to my problem. has anyone any experience in this area and could point me in the right direction

thanks Davon

I think your question or problem is too broad.
Could you explain your problem in more details?
Otherwise people will ignore your post because they don't understand it.
