When you make a transaction with your payzy debit card, the amount may not be a whole number, e.g. €5.40 In this case, we call the rounding of the amount to the next whole number the “change”, i.e. in the example above, the change would be the €0.60 remaining to get to the rounded amount of €6.
All the change generated in this way from your payzy debit card transactions can be saved in your Piggys, as long as you enabled the automated deposit mode.
If at the time of your payzy card transaction there are insufficient funds in your wallet, then the savings will not be completed and a new attempt will be made on your next payzy card transaction.
