Google Play card

[Android Central Question]

My son got a tablet for his bday. I put family link on it with parental controls. But I'm having trouble linking his Google play cards to his account. I keep getting an error with numbers behind it. What do I do?

Welcome to Android Central! Google Play gift cards are only usable by users who are 13 years or older: https://play.google.com/intl/en_us/about/card-terms.html. I'm assuming that your son is younger, since he's on Family Link. See this about using Family Payment: https://support.google.com/families/answer/6294544?hl=en
