What does the error “ETM?” mean when I swipe a credit card? Posted on December 6, 2016December 11, 2018 by Bulldog Tech This error is a connectivity issue, so you should check your internet connection first. Other factors that could cause this are ip address problems or if you renamed the computer hosting the database.
