Safety in numbers
Just like many other payment cards your Acorn Account Prepaid Debit MasterCard® card comes with Chip and PIN. It couldn't be easier to use. Instead of signing a paper receipt to confirm your payment, you enter a four-digit Personal Identification Number(PIN), just like you do at a cash machine. This means it's much harder to be a victim of fraud, as anyone wanting to use your Debit MasterCard card would need to know your secret PIN to make a payment with your Debit MasterCard card.
If you think someone might know your PIN, contact our management team.
Changing Your PIN
We've now made it possible to change your PIN to something more memorable.
To change your PIN, follow these simple steps:
- Insert your Acorn Account Debit MasterCard card into an ATM displaying the MasterCard Acceptance Mark (we recommend using a mainstream high street bank's cash machines for this).
- Follow the on screen instructions and key your PIN.
- From the on screen menu, select the "Change PIN" or "PIN Services" option.
- Follow the on screen instructions to change your PIN.
- You will receive an on screen message confirming your PIN has been changed.
- You will need to use your new PIN when authorising payment and cash withdrawals.
We strongly recommend that you do not change your PIN to a number that is easily guessed such as 1234 or your date of birth. You shouldn't disclose your PIN to anyone, including Acorn staff.
