Yes they were all the VPOS Touch Units. Most of them the chip part of the card reader would not work. If you insert a chip card it would just say transaction cancelled. Would spend hours on the phone with those guys trying to change settings in them but It would never work. They would always end up sending out replacements. Couple of them were sending a constant signal to the
coin pulse on my timer which would put my vacs out of service regardless if a customer used
coin or credit. Once the timer would get that constant pulse after say a customer inserts their first
coin it would display
COIN on the timer display and wouldn't let anything happen because the pulse was not released. Most recently I had one that completely died as if it had no power. Still waiting to receive my replacement for that one. Glad you had some luck with them cause I definitely haven't.
