I thought that magnetic stripe on the back of the tickets is where they get all the info from the pass onto the computers. Last December my Dad had left his pass at home, thankfully we were using the plastic resort cards for our passes (not our Resort ID seperate tickets). Anyway the numbers on our tickets were the same, expect the last digit & when the Cast Member on the Atrium Club floor entered my number our infomation from the tickets showed up with the days we had left on them & the times from last August with what parks we went to.
