How to buy a product on Mundpay with a credit card?

Buying products through Mundpay is simple and safe.
Below, we explain the step by step to correctly fill in the credit card information on the payment page of the product you want to purchase.

Which credit card information is requested?

When choosing a credit card as the payment method, you will need to provide the following information:
Card number
It is the sequence of 16 numbers on the front of the card. Enter the numbers exactly as they appear.
Month and year of expiration
Provide the month (MM) and year (YY) of the card's expiration date, both with two digits. Make sure the card is still valid. If it has expired, you will need to request a new card from the issuing bank.
Security code (CVV/CVC)
It is a sequence of 3 or 4 numbers used for online purchases. Usually, it is located on the back of the card.
If your card does not have this code or is not enabled for online purchases, check if the bank offers a digital card in the app or contact the financial institution directly.

Where to find this information on the card?

In general, the data is located as follows:
A – Expiration date
B – Card number
C – Cardholder name
D – Space for signature
E – CVV/CVC (security code)
F – Magnetic strip

Installment payment

If the responsible seller makes the installment option available for your region, this alternative will be displayed after filling in the card details.
If the option does not appear, it means that installment is not enabled for that product. To confirm if there is a possibility of enabling it, we recommend contacting the seller directly.

Contact of the responsible seller

At the end of the payment page, the information of the responsible seller is available, including:

  • Product name
  • Seller's email

This information can be used if you have questions about the product, payment conditions or delivery.

Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.

FAQ: Frequently asked questions on purchase with credit card on Mundpay

What card information do I need to provide when purchasing?

When you choose credit card as your payment method, you'll need to provide four main pieces of information. First, the card number, which is a sequence of 16 numbers located on the front of the card. Second, the expiration month and year in MM/YY format. Third, the security code CVV or CVC, which is a sequence of 3 or 4 numbers. Fourth, the full name of the cardholder exactly as it appears on the card.

Where is my card's security code located?

The security code, also known as CVV or CVC, is a sequence of 3 or 4 numbers used specifically for online purchases. Typically, this code is located on the back of the card, near the magnetic stripe. If you have a standard debit or credit card, flip the card over to see the back and locate the CVV/CVC number there. If your card doesn't have this code, you can request a digital card from your bank's app.

If my card is expired, can I use it to buy?

No, you won't be able to make a purchase with an expired card. The payment page will check the expiration date and reject the transaction if the card is expired. If your card has expired or is about to expire, you need to request a new card from the issuing bank before making the purchase. Alternatively, you can use a digital card offered by your bank in the app, if available.

How long does it take for a digital card to become available?

The time for a digital card to become available varies depending on the bank and app you use. Generally, the digital card becomes available immediately after you request it in your bank's app, or in some cases it takes only a few minutes. If your physical card doesn't have a security code or isn't enabled for online purchases, check if the bank offers a digital card option in the app. If you can't get one, contact the financial institution.

Can I split my purchase into installments with a credit card?

If the responsible seller makes installment options available for your region, this alternative will be displayed on the payment page after you fill in the card details. The number of available installments depends on the configuration set by the seller. If the option doesn't appear, it means installments are not enabled for that specific product. To confirm if there's a possibility of enabling it, it's recommended to contact the seller directly using the information available on the payment page.

If a field appears in red, what should I do?

If any field on the payment page appears highlighted in red, this indicates there's an error or incomplete data. A number might be missing, you may have entered an invalid character, or the data was typed outside the expected standard. Review this information carefully and try again. For example, if the card number is incomplete or the expiration month is wrong, correct it and try to complete the purchase. If the problem persists, consult Mundpay's Help Center.
