Mini ATM piggy banks are small children's toys or decorative piggy banks that mimic the appearance and functionality of bank automated teller machines (ATMs), but are typically used to store pocket money and small amounts of money, rather than real bank transactions. Here are some features and functions of a mini ATM piggy bank:

Simulated ATM function: Mini ATM deposit boxes typically have the appearance and functionality of simulated bank ATMs. They include digital display screens, card slots, withdrawal ports, password keyboards, and various buttons to simulate ATM operations.

Saving and Withdrawal: Children can use this type of piggy bank to deposit their pocket money and then use a simulated bank card and password for withdrawal operations. Although these operations do not involve actual bank transactions, they can help children understand the concept of money.

Password protection: Some mini ATMs have password protection features that require children to enter the correct password to access their savings.

Digital display screen: The piggy bank is usually equipped with a digital display screen to display the total deposit amount and withdrawal amount, helping children track their savings progress.

Reward system: Some mini ATMs have reward systems that encourage children to actively save. Children can receive rewards or unlock specific content by achieving specific savings goals.

Educational: These piggy banks aim to educate children on the basic concepts of savings, budgeting, and financial management. They can help children develop good habits of saving.

Decorative design: Mini ATM piggy banks usually have attractive decorative designs to meet children's aesthetic taste.
