2 merchants several days ago started to have to swipe their cards 2 or 3 times for cards to go through. They are using RMS 1.2 with Windows XP and using the gateway:
ssl1.tsysacquiring.net/scripts/gateway.dll?Transact
We are in the process of upgrading their systems to RMS 2.0 with Windows 7 and will see if that fixes it. If not, we are guessing it is an issue with tsys and will switch to Vantiv or Heartland.
