A Piggy Bank is simply a way for customers to organise their savings into logical segments that make sense to them, and simultaneously make it slightly difficult to see what balance is inside (balances can be viewed after a 30 second delay).
Piggy Banks are primarily designed for personal use but there are certain business use cases so we have enabled them for business use too.
It is up to you whether you create Piggy Banks or not, and how you use them.
