I appreciate that this maybe linked to your card issuer status but it would be really useful to be able to provide cards to Under 18s.
Banks provide debit cards on childrens accounts when they are 13 I think so chip / pin, etc should be well understood by them.
Obviously with holiday season approaching and the reduced limit on ATM withdrawals it means that families with children may have to revert to traditional old school currency exchanges and take physical cash.
With chip / pin everywhere (especially in Europe) children from a certain age should be able to take advantage of revolut. Leaving the age limit at 18 means they will become more accustomed to traditional banks and not the digital future.
