Hi There,
I am the right person for this job , as i do have done integration of card machine with POS application.
I have worked with payment sense, YesPay, verifone(Setinel)
I can do that but need PDA device at your end to do testing ,
and it will take 30 to 40 days in integration, plus accreditation test also need to be done with all.
if you are open for budget then we can do this.
Regards,
Raj
