There are 2 possibilities:
By invitation from a parent
If a parent already has an account with Clanq powered by Cornèr, they can invite their family and anyone else who wants to join them in saving. The invitation via the app automatically links one or more selected piggy banks. Invitees do not have to open an account, but can still easily pay into their child's piggy bank and collect cashback.
Open an account yourself
You can also open an account with Clanq powered by Cornèr if you don't have a child of your own. Although the app is intended for parents, it is open to anyone who wants to put money aside for a child's future - whether it's a grandchild, godchild, nephew or fourth cousin.
