Fraude por devoluciones de cargos en tarjetas de crédito: guía de prevención para comerciantes

Credit card chargeback fraud is when a cardholder disputes a valid card payment with their bank to get the money back while keeping the goods or service. The merchant loses the sale, pays a chargeback fee, and takes a hit to its dispute ratio.

Fraudulent chargebacks usually come with a false claim. The cardholder says they did not make the purchase, the order never arrived, or the item was not as described. This guide covers the credit card angle: how to tell the fraud types apart, what they cost, how to prevent them, and which evidence wins each claim.

Types of Credit Card Fraud Behind Chargebacks

Credit card fraud is a concern for both consumers and merchants. It reaches merchants in three main forms: chargeback fraud, friendly fraud, and identity theft. Each one starts differently, and each one needs a different response.

Scroll to compare all columns. Use the arrow keys when the table is focused.

1. Fraude por devolución

Chargeback fraud occurs when a customer disputes a legitimate transaction with their bank or credit card company. If the bank sides with the customer, the transaction is reversed and the merchant receives a chargeback.

It can happen in several ways. The customer may claim they never received the product or service. Or they may claim it was defective or not as described, even though it was not.

2. Fraude por parte de personas conocidas

Friendly fraud happens when a customer disputes a charge without any malicious intent. They may forget they made a purchase. Or they may not recognize the merchant's name on their credit card statement.

Friendly fraud can also occur when a customer is unhappy with a product and goes to the bank instead of the merchant, even if the merchant delivered as promised.

3. Robo de identidad

Identity theft is a type of credit card fraud where someone steals another person's personal details, such as their name, address, and credit card number, to make unauthorized purchases. The fraudster may use that information to open new credit card accounts or to buy with the victim's existing cards.

Identity theft can be devastating for the victim. Clearing the fraudulent charges and repairing their credit score can take a long time. For merchants, these orders are often card-not-present fraud. Unlike chargeback fraud, the chargeback is usually valid.

Repercusiones del fraude por devoluciones de cargos en tarjetas de crédito para los comerciantes

Credit card chargeback fraud hurts merchants in three ways: financial losses, a damaged reputation, and operational disruption.

1. Pérdidas económicas

Each fraudulent chargeback costs more than the sale. The merchant loses the revenue, the product, the shipping cost, and the chargeback fee.

The LexisNexis True Cost of Fraud study puts the total cost for US retail and ecommerce merchants at $5.13 for every $1 of direct fraud loss. A high chargeback rate can also lead to higher processing fees and a worse risk rating. That makes payment processing harder and more expensive to keep.

2. Daño a la reputación

Chargeback fraud can make a merchant look careless to banks and processors. It suggests weak products, weak service, or weak security. If chargeback fraud keeps rising, the merchant can end up in a card network monitoring program, with fines and closer review.

3. Interrupción de las operaciones

Every chargeback fraud case takes staff time. Teams have to investigate the order, collect evidence, write a response, and add new security checks. This raises labor costs and pulls focus away from running the business.

Estrategias para prevención el fraude por devoluciones de cargos en tarjetas prevención

You cannot stop every fraudulent chargeback, but you can cut most of them before they reach the bank. These four strategies help you prevent chargeback fraud at the main entry points.

1. Verificación de la identidad del cliente

Merchants can prevent chargeback fraud by verifying customer identity before processing transactions. Check the billing address, CVV code, and IP address. For high-value orders, you can also ask for extra proof, such as a photo ID, to stop identity theft.

2. Uso de herramientas de detección de fraudes

Fraud detection tools flag suspicious transactions and likely chargeback fraud before you ship. They use machine learning, behavioral analysis, and transaction monitoring. Pre-dispute alerts such as CDRN and Ethoca alerts add a second layer. They let you refund a disputed order before it turns into a chargeback.

3. Ofrecer un excelente servicio de atención al cliente

Good customer service helps prevent chargeback fraud by stopping many disputes before they escalate to chargebacks. Reply to customers quickly. Give clear and accurate product information. Offer a fair, easy refund path, so a refund feels simpler than calling the bank.

4. Elaboración de políticas claras

Clear policies prevent chargeback fraud by reducing misunderstandings and disputes. Publish concise product descriptions, shipping and delivery policies, and return and refund policies. Show them at checkout, and make customer support easy to reach.

Which Evidence Wins Each Type of Fraudulent Chargeback?

The right evidence depends on the claim the cardholder made. Banks review the reason code first, so match your proof to it. The table below maps the most common credit card claims to the evidence that answers them.

For "I did not make this purchase" claims on Visa, Visa Compelling Evidence 3.0 can shift liability back to the issuer.

Under Visa's rules, effective April 15, 2023, you need at least 2 earlier undisputed transactions on the same card. They must be 120 to 365 days old and share at least 2 data points with the disputed order. One of them must be the IP address or device ID.

Medidas que se deben tomar en caso de fraude por devolución de cargo en tarjetas de crédito

When chargeback fraud hits, speed and evidence decide the outcome. Follow these three steps.

1. Respuesta a Contracargos

Respond to chargeback fraud fast, with a clear and short rebuttal backed by evidence. Submit it within your processor's deadline, or you lose the right to dispute. Card networks and processors set different chargeback time limits, so check yours for each dispute. Keep a record of every message and file you send.

2. Recopilación de pruebas

To win, you need compelling evidence that fits the claim. This may include shipping and tracking details, order details, and customer messages. Be ready to add more, such as login history or other records that prove the transaction was valid.

3. Resolución de litigios

If a chargeback dispute cannot be resolved with the customer or their bank, use your payment processor's dispute process.

The issuing bank reviews your evidence and decides. If you lose and still have a strong case, the dispute can go to pre-arbitration and then arbitration, where the card network rules on it. Stay responsive and send complete documents at every stage.

You can also act before disputes start. Use address verification, CVV checks, and transaction monitoring, and watch reward balances for loyalty program fraud. Make sure your customer service policies are clear and easy to find.

Credit Card Chargeback Fraud FAQs

Is credit card chargeback fraud illegal?

Yes. Credit card chargeback fraud, filing a dispute you know is false to keep both the goods and the money, is a form of theft by deception in most countries. Criminal cases are rare for small amounts. More often, the issuing bank reverses the refund, closes the card, or blocks future disputes.

What happens if a customer files a fraudulent chargeback?

When a customer files a fraudulent chargeback, the merchant's funds are pulled back and a chargeback fee is charged. The merchant can fight it by sending evidence to the issuing bank. If the bank accepts the evidence, the money returns to the merchant and the cardholder is charged again.

Can merchants win fraudulent chargebacks?

Yes. Merchants can win fraudulent chargebacks when their evidence matches the reason code. Tracking and delivery proof answers "not received" claims. AVS, CVV, IP, device data, and Visa Compelling Evidence 3.0 answer "I did not make this purchase" claims.

How can merchants prevent chargeback fraud on credit card payments?

Merchants prevent chargeback fraud on credit card payments by checking AVS, CVV, and 3D Secure at checkout, using fraud detection tools and pre-dispute alerts, and making refunds easy to request. Clear billing descriptors and fast support stop many friendly fraud disputes before they reach the bank.

How can merchants tell friendly fraud from true fraud?

Friendly fraud comes from the real cardholder, so order data usually matches their history.

Look for the same device, IP, address, and account. True fraud is credit card fraud by a third party, so it usually shows a new device, a mismatched address, or a failed AVS or CVV check. Matching data points to friendly fraud or chargeback fraud, which merchants can often dispute.
