I'm not sure if it's simply coincidence, but I've noticed that while most new ATMs (in the US) are swipe only, it seems that on ATMs that allow deposits the machine retains the card. I'm not sure if there's a reason the card is retained for deposits. I also could just be tricking myself with anecdotal evidence, but I've definitely seen new ATMs side by side with a swipe withdrawal-only and a retaining withdrawal-and-deposit.
