AU Small Finance Bank Debit Card Activation and PIN Generation Process

AU Small Finance Bank has made most of the initial debit-card setup a self-service process. Once your bank account is active and the debit card has reached you, you can create your own four-digit PIN instead of waiting for a separate PIN mailer. The process can be completed through AU’s website, AU 0101 digital banking, an AU ATM or the bank’s IVR service.

The debit card PIN is required for ATM withdrawals and PIN-authenticated merchant transactions. However, setting the PIN does not automatically switch on every type of card usage. Under AU Small Finance Bank’s current card-security settings, online/e-commerce, contactless and international transactions are disabled by default and have to be enabled separately if you want to use them.

AU also allows customers to reset a forgotten debit card PIN, temporarily block or unblock a card, control domestic and international transaction channels and set separate limits for ATM, POS, online and contactless transactions through AU 0101.

What Do You Need to Set Up an AU Debit Card?

Keep the following ready before starting:

• AU Small Finance Bank debit card
• 16-digit debit card number
• Debit card expiry month and year
• Customer ID
• Mobile number registered with AU Small Finance Bank
• PAN or date of birth when required
• Access to the registered mobile number for receiving OTPs
• AU 0101 credentials if using Mobile Banking or NetBanking

For IVR-based PIN generation, you should call from the mobile number registered with the bank.

How to Activate an AU Small Finance Bank Debit Card

AU allows customers to complete debit-card setup digitally. Once your account is activated, you can generate the card PIN through one of the bank’s supported channels and start using the card for permitted transactions.

A convenient first-time process is:

1. Generate your four-digit debit card PIN.
2. Complete the required OTP or customer verification.
3. Confirm that the PIN has been set successfully.
4. Make a small ATM or POS transaction to confirm that the card is working.
5. If you want to shop online, use contactless payments or make international transactions, separately enable those card channels.

AU’s official debit-card guidance also confirms that card activation can be handled from home through its digital debit-card services instead of requiring a branch visit.

AU Small Finance Bank Debit Card PIN Generation Through Website

AU provides a dedicated debit-card management facility on its official website. This is one of the clearest methods for setting the PIN for the first time.

Follow these steps:

1. Open the AU Small Finance Bank debit-card management page.
2. Enter your 16-digit debit card number.
3. Enter the card expiry month and year.
4. Submit the card details.
5. Enter your Customer ID.
6. Verify yourself using either:

• Date of birth, or
• PAN

1. After successful verification, an OTP will be sent to your registered mobile number.
2. Enter the OTP.
3. Enter the new four-digit debit card PIN you want to use.
4. Re-enter the same PIN for confirmation.
5. Submit the request.

Once the PIN is successfully set, you can use it for subsequent eligible debit-card transactions.

The website also provides card controls that can be used to switch online transactions on or off.

AU Debit Card PIN Generation Through an ATM

You can also generate the PIN at an AU Small Finance Bank ATM.

Follow these steps:

1. Visit an AU Small Finance Bank ATM.
2. Insert your debit card.
3. Select Set your Debit Card PIN or Set Debit Card Green PIN.
4. A six-digit OTP will be sent to your registered mobile number.
5. Enter the OTP at the ATM.
6. Enter your preferred four-digit debit card PIN.
7. Re-enter the same PIN for confirmation.
8. Complete the request.

After successful verification, the PIN is set and can be used for eligible card transactions.

Use an AU Small Finance Bank ATM for the bank’s own Green PIN setup process rather than assuming that another bank’s ATM will provide the same options.

1. Enter the information requested by the IVR.

What If You Forget Your AU Debit Card PIN?

You do not need to remember the old PIN before setting a new one.

AU provides PIN regeneration through:

• AU 0101 App
• AU 0101 NetBanking
• AU website
• AU ATM
• Customer Care IVR

For example, through AU 0101 simply select Debit Card → Regenerate PIN, enter the card expiry details and choose a new PIN.

Avoid repeatedly guessing the old PIN because repeated incorrect attempts can cause the card to be temporarily restricted.

How to Enable Online Transactions on an AU Debit Card

Online transactions are disabled by default under AU’s current debit-card security controls.

To enable them through AU 0101:

1. Log in to the AU 0101 App.
2. Select Debit Card.
3. Select the required card.
4. Go to Transactional Usage.
5. Click Enable/Disable.
6. Select Domestic Usage.
7. Switch Online transactions ON.

You can also control how much can be spent through different card channels.

Through the AU 0101 App:

1. Log in and select Debit Card.
2. Choose your debit card.
3. Select Set Limits.
4. Set appropriate limits for:

• ATM cash withdrawals
• POS purchases
• Online transactions

1. Submit the changes.

You can increase a limit only up to the maximum permitted for your particular debit-card variant.

How to Enable International Transactions

International debit-card usage is disabled by default.

If your card supports international transactions, you can enable them through AU 0101.

Follow these steps:

1. Log in to AU 0101.
2. Select Debit Card.
3. Open Transactional Usage.
4. Select Enable/Disable.

1. Select Confirm.

International card usage is updated after successful OTP verification.

For security, international usage can be kept disabled when it is not required.

How to Enable Contactless Transactions

A contactless-enabled AU debit card will not necessarily work for tap-and-pay immediately because contactless transactions are disabled by default.

To enable them:

1. Open AU 0101.
2. Select Debit Card.
3. Open Transactional Usage.
4. Choose domestic or international usage as required.
5. Switch Contactless usage ON.
6. Confirm the request.
7. Verify through OTP.

You can separately set the contactless transaction limit through the card’s limit controls.

How to Temporarily Block or Unblock an AU Debit Card

If you have misplaced the card but believe you may recover it, AU 0101 allows temporary blocking instead of immediately requesting permanent closure.

1. Log in to AU 0101.
2. Select Debit Card.
3. Select Block this Card.
4. Choose Temporary Block.
5. Complete the verification.

The app also provides permanent blocking if the card is genuinely lost or stolen. A permanently blocked card should not simply be treated as a forgotten-PIN case.

What Should You Do After Setting the AU Debit Card PIN?

After the PIN has been successfully generated, make a small ATM or merchant transaction to check that the card works correctly.

It is also sensible to:

• Enable online payments only if you need them.
• Keep international usage disabled unless required.
• Set reasonable ATM, POS and online limits.
• Enable contactless transactions only according to your needs.
• Never share your card PIN with another person.
• Never disclose an OTP, CVV or banking password to anyone.
• Permanently block a card immediately if it is lost or stolen.

What If AU Debit Card PIN Generation Fails?

Before trying again, check whether:

• Your AU bank account has been activated.
• The debit card number is correct.
• The card expiry details are correct.
• The Customer ID is correct.
• Your date of birth or PAN matches the bank’s records.
• Your mobile number registered with AU is active.
• You are entering the latest OTP.
• The card has not been permanently blocked.

If you are using IVR, remember that PIN generation is available only when the call is made from the registered mobile number.

If the problem continues, contact AU Small Finance Bank Customer Care at:

1800 1200 1200

This is the bank’s current toll-free number for banking and debit-card assistance.

FAQs

1. Can I generate an AU Small Finance Bank debit card PIN without visiting an ATM?

Yes. An ATM visit is not compulsory. You can set the four-digit debit card PIN through AU Small Finance Bank’s website, AU 0101 digital banking or Customer Care IVR. The website process uses card details, Customer ID, PAN or date of birth and OTP verification.

2. Why does my AU debit card work at an ATM but not for online shopping?

Online or e-commerce transactions are disabled by default. AU follows separate card controls for ATM, POS, online and contactless transactions. Open AU 0101, select the debit card, go to Transactional Usage, enable Online transactions and set an appropriate limit before retrying the payment.

3. Can I reset my AU debit card PIN if I do not remember the old PIN?

Yes. AU 0101 App and NetBanking provide a Regenerate PIN facility. Select the debit card, enter its expiry details and create a new PIN after completing the required authentication. You can also use the website, ATM or IVR Green PIN service.

4. Can ATM, POS, online and contactless transactions be controlled separately on an AU debit card?

Yes. AU allows customers to individually enable or disable ATM, POS, online and contactless usage under domestic and international card controls. Separate transaction limits can also be set for these channels, subject to the maximum limit available for the particular card variant.
