There could be several reasons why you can’t pay online using your Mastercard, including having insufficient funds or making errors when introducing your card details. You should also make sure that your Mastercard is activated before attempting to make a purchase.
Reasons Why You Can't Pay Online With Your Mastercard
- Insufficient Funds: Ensure that you have enough funds or available credit in your account to cover the transaction you're attempting to make. You can log in to your online account or use the issuer’s mobile app to check your account details.
- Activation: If you've recently received a new Mastercard, make sure that you've activated it according to the instructions provided by your card issuer. An inactive card won't be able to process transactions.
- Card Expired: Check the expiration date on your Mastercard to ensure that it hasn't expired. It should be located on the front of your card, below the card number. If it turns out that your Mastercard has expired, you'll need to contact your issuer to request a replacement.
- Incorrect Card Details: Double-check that you've entered the correct card number, expiration date and security code when making your online payment. Even small errors in these details can cause transactions to fail.
- Fraud Protection Measures: Your Mastercard issuer's fraud protection system may be flagging the transaction as fraudulent. There can be quite a few transactions that can trigger your company’s fraud monitoring system, like abnormally large purchases or multiple transactions in a small amount of time.
Ultimately, the most straightforward way to learn why your Mastercard can’t be used for online purchases is to contact customer service at the number you see on the back of the card. A customer support agent can provide personalized support and guidance to help resolve the issue and ensure that you're able to use your Mastercard for online transactions smoothly in the future.
