We are in WDW now and we came with paper no expire tickets. Going thru the turnstylres at our first park we were directed to a castmember with a hand held device. He scanned us in and told us to get our tickets converted at guest services when we could. They worked just fine in the fastpass machines. We converted them in the evening when we were leaving our first park b/c there was no line at guest services. My husband joined us a few days later. He used his paper ticket in 2 parks, fastpass machines and DQ. It had to be hand scanned at the park entrances. We finally converted it at the outside DQ guest services window. The castmember explained that it is the same old ticket just in a new exterior shell. Hope this info helps.
