Setting up your Yoti account involves uploading details from your identity documents and we carry out biometric checks to stop people setting up fake identities. There are different laws in different countries about how an organisation can collect and use children's information.
There are also different laws on collecting and using biometric information. All these laws say when you need a parent or guardian's consent to do so, and they all have different ages for when this is needed. In some countries you have to get parental consent to collect any information from a child, in other countries you only need parental consent for biometric information.
