Pocket money app Rooster Money is branching out with a new Visa prepaid card for kids, ramping up its rivalry with the likes of popular children's money card GoHenry.
Children will be able to use the new prepaid card in shops, at cash machines and for online purchases. But - crucially - parents will be able to keep a watchful eye over their kids' spending.
But how does Rooster Money compare to other kids banking services?
Rooster Money has traditionally been a pocket money app since it launched in 2016, with no options for children to spend their money themselves. But a will be available from June, and you can join a waiting list now.
The Visa prepaid card will have a CVV number, which means it can be used to make purchases online, as well as at cash machines and in stores. Parents have the option to switch off any of these features.
The card can't be used in shops that have an over-18s merchant code, and there's no overdraft facility, meaning your child can't get into debt.
While the app helps kids track their pocket money, earn rewards and save towards certain goals, the prepaid card adds extra features.
The account has a sort code and account number, so family and friends can pay in gift money.
The CVV number, which can only be accessed in the app, changes after every purchase, making it a secure way to pay.
Both children and parents receive real-time spending notifications. The card can be frozen and unfrozen through the app at any time if it gets lost.
You child's money can be split into four pots. Only cash in their 'spend' pot can be spent on their card. Other pots include 'save' (for savings), 'give' (for supporting a cause or charity) and 'goals' (for saving for something specific), all of which parents can control.
This ensures kids can only spend the money they're supposed to.
If you have more than one child on the app, they'll be dealt with separately, which is ideal if you feel one child is too young for the card, but the other is ready.
Rooster Money says its app is suitable for children as young as three or four-years old, but the prepaid card is aimed at six to 18-year olds. Parents can choose to introduce the prepaid card whenever they feel their child is ready.
The prepaid card will be a premium feature, but the fees are yet to be confirmed.
Update: Rooster Money has now confirmed that the fees will be £24.99 per card, per year.
Rooster Money is not the only app or prepaid card that introduces younger children to the world of money management. So it's worth shopping around to find the best product for your family.
Ages: 6 to 18
Features: If you have more than one child, parents can manage all of their finances through this app. There's a parental online account, with links to each child. You can set tasks that will mean your kids will earn more money, set limits for spending and invite relatives to contribute to the account. The kids will have a prepaid card, and parents can specify where this can be used.
Fees: £2.99 per child, per month (£35.88 a year).
Ages: 8 to 18
Features: Kids get a prepaid card which connects to the app, which will show how much they've spent and their remaining balance. Parents have full visibility over what their children are buying, and can set up a regular allowance, locks and limits.
Fees: £2.50 per child, per month (£30 a year).
Ages: 8 to 18
Features: Similarly, Nimbl's prepaid card links to the app and gives spending overviews for both children and parents. There's a micro-savings feature, where children can save between 5p to £5 whenever they spend, plus parents can set up instant top-ups, spending alerts and controls. Cash gifts can also be sent directly to the account.
Fees: £15 per card, per year.
Larger banks and building societies will often let children open current accounts from the age of 11, but some are restricted to those aged over 16.
The three children's bank accounts with the highest customer ratings are:
The Which? Customer Score is the rating for customer satisfaction, based on feedback from 4,255 real customers who were surveyed in August 2018. The score is made up of a customer's overall satisfaction with the brand, and how likely they are to recommend that brand to a friend.
While 16-year olds can generally open an account themselves, parents or guardians will need to open younger children's accounts.
You'll usually need to go into a branch, and provide a birth certificate or passport, plus a recent household bill or bank statement as proof of address.
Children are liable to pay tax in the same way as adults on their savings interest, so bear this in mind if you're planning to give your child a significant sum of money.
However, parents may still be on the hook to pay tax. If the interest on the savings you deposit into your child's account exceeds £100 a year before tax (or £200 if both parents give money), all interest will be added to your own and taxed as if it were your own.
