I'm unsure about contactless myself - It seems to choose usability over security - yes there might be limits and it may occasionally ask for a pin but if it is used fraudulently I wonder how easy it will be to get your money back.
However there is also another worry - It seems there is a possibility of cards being scanned by cyber criminals, criminals trying to scan cards from a distance to steal data. There are already wallets available now with RFID blocking technologies, designed to avoid this type of situation.
