I just came across Spriggy | Pocket Money. Updated. - a VISA debit card for kids with an app and tools to manage spending and pocketmoney etc. Spriggy builds important money habits in an environment where practical financial skills are rare to come by. Our prepaid card and purpose-built mobile app help teach 6-17 year olds vital earning, saving and spending skills with real world practice. Pricing is $30 per year per child (with no extra fees except for replacement cards and overseas transactions). Anyone have any experiences with this for their kids? What ages is it ideal for? Do kids need their own phone for this to be useful?
