What is POS Security? Keeping Your POS System Safe

Point of sale (POS) systems are beneficial for retailers and customers alike, since they allow consumers to easily make purchases with the swipe of a card. However, with that ease comes the potential for security breaches. POS security problems cost companies money for fraudulent charges, and possibly even fines. They also significantly erode consumer trust. This makes keeping your POS system safe from the prying eyes of cybercriminals particularly important.

And for good reason: In recent years, companies like Forever 21, Wendy’s, and Rutter’s have been the victims of POS security breaches. But your customers’ information and your reputation don’t have to become casualties of these threats. The following POS security tips can help you safeguard both.

Maintain Dedicated Devices for POS System

One significant way to keep your POS system safe is to maintain dedicated devices that are used solely for the purpose of customer transactions. This minimizes opportunities for cybercriminals to attack the system. Whether you’re using an iPad or terminal, keeping sales transactions separate creates a more secure environment for customer information.

Use Encryption

Encrypting customers’ credit card numbers and other sensitive information is another important way to boost your POS security. Encryption ensures that even if hackers get into the system, the information they obtain is useless. They would need a code to view the data they’ve stolen.

Install Antivirus Software

Keep the data in your POS system safe by using robust anti-virus software—just as you would with a computer. Remember that customer information is being transmitted through the Internet, so this kind of protection is imperative.

Use antivirus programs to scan for issues—like malicious files or software—that may lead to a cyberattack. That way, you can stay abreast of any potential vulnerabilities criminals can exploit and remove them immediately.

Update Software Regularly

POS security is constantly evolving. Thieves need to evolve their tactics along with it in order to outsmart these systems. But they won’t get the opportunity if your POS system is regularly updated. Be sure to download software upgrades regularly—preferably by setting up automatic updates. You will stay steps ahead of hackers when you do.

Keep Your Network Secure

To help keep your POS system safe, it’s a good idea to make sure the network it’s connected to is tight. Don’t connect to external networks because that can be an open door for hackers to get into your system. Use an internal network that is localized and secure instead.

Additionally, create strong passwords for your network that are difficult to guess—and remember to change them regularly. Don’t allow your customers to have guest access to your network. Only share the password with staff members on a need-to-know basis.

Setting up two-factor authentication is an additional precaution you can use, just in case your password does get into the wrong hands.

Adhere to Industry Standards

The Payment Card Industry Security Standards Council (PCI SSC) oversees the standards that companies are expected to adhere to when accepting credit cards. Card readers, networks, routers, and servers are expected to be in compliance with the Payment Card Industry Data Security Standard (PCI DSS).

One way to achieve PCI DSS compliance is by getting rid of cardholder information whenever possible, so there is no data for hackers to find. Also, the PCI SSC recommends communicating regularly with credit card providers about theft issues.

Train Your Employees on POS System Safety

You can put all of the security protections in the world in place, but none of them will mean much if your employees don’t understand how to keep your POS system safe. Provide regular training so employees know security best practices. Teach them how to avoid phishing schemes and protect login information.
