I thought about trying to use it at Wendy's then I saw they had the tiny little card swiper attached to their monitor so I just did not bother plus I was in a hurry & did not feel like testing to see if it would work.
Yep, works. Regardless if the strip reader is attached to the monitor. If the reader is on either the monitors left or right edge, I hold my S3 up to it. if I can't reach the reader with my wrist, then I use other forms of payment.
