Restaurant banking fraud: protect your card payments

Credit card fraud is a growing challenge in the restaurant industry. With the rise of contactless payments, the speed of transactions and the use of certain obsolete tools, restaurateurs are particularly exposed to this risk. Undetected fraud can have serious consequences: financial losses, damage to reputation and increased bank charges. So how can you effectively protect your establishment against these threats? In this article, we review the main risks and the best solutions for securing your transactions.

‍

Why are restaurants vulnerable to fraud?

Rapid customer turnover

In a restaurant, customers come and go in quick succession, especially at peak times. This makes it difficult to monitor transactions and detect fraudulent payments.

Transactions carried out under pressure

Staff are often under pressure to collect payments quickly. This time pressure reduces vigilance and can allow a fraudster to go undetected, especially if the card used is stolen or cloned.

Expansion of digital payments

The rise of digital payments facilitates transactions, but also introduces new risks. Contactless, Tap to Pay, QR code payments and Click & Collect allow customers to pay quickly, often without identity verification. If the contactless ceiling is too high, or if online payments do not require additional validation (such as 3D Secure), fraudsters can exploit these loopholes to use stolen or spoofed cards.

Obsolete or uncertified tools

Using an obsolete or uncertified cash register increases the risk of fraud. Some tools lack the latest security updates, exposing transactions to hacking attempts.

What are the risks for restaurateurs?

Financial loss

A fraudulent transaction can cost your restaurant dearly. If a payment is disputed by a fraudulent customer who has never visited your establishment, either physically or online, you run the risk of not being reimbursed by the bank. 

What's more, if the number of disputes increases, insurance companies and banks may decide to tighten their conditions or apply financial penalties. 

Damage to reputation

A customer whose bank details are stolen when paying in your restaurant may lose confidence. Not only will they not return to your establishment, but they may also leave reviews or share a negative experience on social networks, which will damage your image.

Additional bank charges

A restaurant subject to repeated fraud may see its bank charges increase. Banks may apply additional charges to compensate for the risks, making transactions more expensive.

How can you protect your restaurant against bank fraud?

Modernizing payment terminals

One way to prevent credit card fraud is to invest in modern, up-to-date payment terminals. New models incorporate advanced technologies to detect suspicious transactions and combat fraud. They also offer regular updates to enhance security in the face of new fraud techniques. What's more, some models offer a secure connection to your cash register systemguaranteeing better transaction traceability.

Use NF525-certified tools

In France, the NF525 standard standard is essential to ensure the compliance of cash register and payment systems. A certified system ensures transaction security and reduces the risk of fraud. This standard also guarantees the inalterability of data, protecting your establishment in the event of a tax audit. Adopting compliant cash register software also helps build a climate of trust with your customers, who feel more protected.

Also consider solutions such as IO Paywhich comply with current regulations and guarantee secure, traceable transactions. They enable restaurateurs to protect themselves effectively against fraud, while ensuring optimal payment management and improving the customer experience.

Train your team to spot bank fraud attempts

Make your staff aware of the warning signs:

  • Customers who hesitate or change bankcards several times.
  • Repeated PIN code refusals.
  • Transactions involving unusually high amounts

A well-trained team can thwart fraud attempts before they become reality. It's important to organize regular training sessions to maintain a high level of vigilance. Encouraging your staff to report any suspicious behavior can also help detect fraud more quickly and enhance the security of your establishment.

Setting security ceilings for contactless payments

Set terminals to require a PIN code above a certain amount (e.g. 50 ). This adds a layer of security to limit fraud on contactless payments.

It is also recommended to set up a random verification system for contactless payments, to encourage consumers to enter their code more regularly and thus reduce the risk of misuse of a stolen card. 

Finally, be sure to communicate these security measures to your customers. Clearly display payment limits, and encourage the use of more secure payment methods such as strong authentication (3D Secure) for online payments.

Credit card fraud is a very real risk for restaurateurs, but it can be prevented by adopting the right reflexes. Modernizing your payment tools, using certified systems, training your staff and implementing contactless limitations are all ways of reinforcing the security of your establishment and protecting your sales.

By taking the lead, you're not just protecting your restaurant from fraud, you're showing your customers that you take their security seriously. A secure payment is a reassured customer, and a reassured customer is a loyal customer.
