Okay, just to let you know, MANY of the kiddie games/apps that kids play on tablets.... costs money. Real, money. In order to upgrade or get more "stuff" or tokens or characters for the games/apps.
But a kid does not know this. They click "yes" and then they get more stuff for their game/app. Then, you the parent, gets the bill for it.
Therefore, you have to set up your account etc., with a password etc., so that the kiddos CANNOT, just "buy" things themselves.
And you have to supervise them and teach them... about this stuff.
When my son was about 4, he "bought" more do-dads for his app. On our iPad. He did not know... it was "real" money. He thought that by clicking "yes" he was just buying it with the pretend tokens on his game, which he thought he had accrued/earned by playing the different levels of it. But no, it was REAL money. And my Husband got a bill for it. It was like $70.
So then, we realized, that MANY MANY MANY of the kiddie games/apps.... ALSO have on it, a pop-up screen to buy more do-dads for their games. BUT it is real, money. And the games/apps make it so "easy" for kids to do this. It just looks like they are playing, their game. Many games have on it, pretend "coins" that they get, OR, they can "buy" stuff for real. On it.
But sure, it can also be fraudulent use of your credit card, by someone you don't even know etc.
Ask your child... did he... "buy" anything via his apps/games on the tablet????/ A kid doesn't know, off hand. But so now, both my kids are very aware of those sneaky things on games & apps, that are to buy things with real money. Even for me as an adult, some of those click on things in games, are very deceiving. You gotta READ it carefully. Or you will be paying with real money.
And teach your kids they CANNOT, buy anything without your permission. AND you teach them, how to use it. By doing it, WITH them.
You gotta know... what apps/games your kid has. And you need to know how to play it TOO... so you are full aware of its parameters.
Some games are real money. Some are not.
