There’s now an Apple Pay smart debit card for kids — 9to5Mac — “With Greenlight, the money you give your child is divided into two categories: money they can spend anywhere, and money they can spend only at a store (or a kind of store) you’ve approved in advance… Greenlight is also turning on Apple Pay support for kids who can add the smart debit card to Apple’s Wallet service on the iPhone, iPad, Apple Watch, and Mac.”
