I remember when contactless was introduced in France, someone from the CB bank card group (https://en.m.wikipedia.org/wiki/CB_Bank_Card_Group) said that contactless was secure because you are insured. At that time France was already using chip+pin for a while.

At the end of the day the money only goes from one bank account to another, account can be frozen, charge reversed, ... So you just need to secure the POS enough that user feel safe to use it and there is a low number of people that can hack them and are willing to risk prison.
