I'll be travelling to Amsterdam/Belgium with my husband and 15 year old in mid-October. RS guidebook says that contactless pay (tap on/tap off) is common, however there are caveats. Each person travelling needs their own payment card. For families that means each person needs their own. Here is my question - my 15 year old doesn't have a credit card (only a debit card). My husband and I have had credit card fraud issues in the past, so we now travel with one main credit card (and only use the 2nd for emergencies in case something happens to the main one). Our international train tickets to/from Belgium have already been purchased, however we plan on taking/paying for local trains, trams, metro and buses as we go.
While we share the same CC account, each card has a separate CC number so I am guessing this would still work for me and my husband, but now I am not sure. Also, what do I do for our teen? Help me please.
