Better Internet for Kids

There are different ways to check someone's age online. 

	The easiest way is self-declaration when you   confirm you're old enough to use a service (like being over 18) by checking a box or clicking a button, or sometimes you might be asked to type in your age.
	You can also show a passport or ID card through your camera so the website or app can check who you are and your birth date. Sometimes, they might ask for your credit card details to prove you're over 18.
	Computer systems can use artificial intelligence (AI) to guess your age by looking at your face or by watching how you use digital services, such as websites and apps.
	Some companies work as trusted third parties to provide digital proof of age. They might get this information from trusted sources like governments or banks. This proof is stored in an app on your phone, which can simply answer "yes" or "no" when services ask if you're old enough.

Remember that each way of checking age has different levels of reliability, and each has its own good and bad points.
