Its written in a click-bait style (what news story isn't these days?) but the only take-home here for parents is that smartphone==credit card. The other issue is that usually for physical credit cards, its easy for a parent to keep it off limits. But if you're signed into services that can auto-charge you, things are a bit more tricky. Even if you had a separate account for your child, and only use a CC to authorize on a per-transaction basis, services can auto-save your CC info, and bury this fact inside some 20 page ToS.
That is true, I guess I was thinking more of a "stole $10 from the kitchen drawer to buy candy" kind of child, not a "impersonated dad, and wired entire life savings to russia" kind of child.
Rifling through a wallet for cash and doing it for the credit card in the next pocket are basically the same action to a child who doesn't know better. And it's not like it's a good or reasonable idea for parents to come home and lock up their wallet in a safe.
