HERE'S MY 2 CENTS. wHEN i WAS WORKING AT ERAC (COUPLE YEARS AGO) EVERY OFFICE HAD TO HAVE A CC IMPRINT MACHINE AND THE TOLL FREE #S FOR THE CC COMPANIES. iF A CARD WOULDN'T SWIPE YOU GET THE PHYSICAL IMPRINT AND CALL IN FOR AN AUTHORIZATION # TO THE CC COMPANY. iF THIS IS DONE THERE IS NO WAY FOR THE CHARGE TO BE CHARGED BACK AS LONG AS THE FINAL SALE IS EQUAL OR LESS THEM THE AUTH.
As for an earlier post that the ee might have been new, I disagree. When i worked for ERAC they never put new employees at the Airport. Most of the Canadian airport locations required MA or above. Exceptions made for star MTs with lots of experience.
