Perhaps I'm not as travelled as you, but none of the similar systems that I
have used ever require you to touch out.

You have to touch out of an Amsterdam tram (the fares are zonal).

"Always check in and check out

Travel with the OV-chipkaart means that you must always check in
and check out at the gates or the yellow card readers."

travel-products/Pages/rules.aspx

It is "unresolved journeys" that cause most Oyster **** ups and is
something that no other system I have used can ever suffer from.

"Not checked in or out? That means there is an incomplete
transaction on your card. Your card will be disabled if there
are twelve incomplete transactions on your card in two weeks.
You must then get the card restored at one of our Tickets & Info
service points."

I wonder if the Singapore system is the same (another of the Oyster-
alikes).
