Exploring the Security Features of mPOS Systems in the UK

Mobile point-of-sale (mPOS) systems are becoming increasingly popular in the UK, as they offer a convenient and flexible way for businesses to accept payments. However, with the rise of mPOS systems, there has also been an increase in security concerns.

In this blog post, we will explore the security features of mPOS systems in the UK. We will discuss the different security measures that are in place to protect cardholder data, and we will also provide tips for businesses to stay safe when using mPOS systems.

What is an mPOS system?

An mPOS system is a portable device that allows businesses to accept payments with a mobile phone or tablet. mPOS systems typically consist of a card reader that plugs into the headphone jack of a mobile device, and a mobile app that is used to process payments.

Why are mPOS systems becoming popular?

There are a number of reasons why mPOS systems are becoming popular in the UK. First, they are very affordable. mPOS systems can be purchased for a fraction of the cost of a traditional point-of-sale (POS) system. Second, mPOS systems are very portable. This makes them ideal for businesses that operate out of multiple locations, or that need to be able to accept payments on the go. Third, mPOS systems are very easy to use. This makes them a good option for businesses that do not have a lot of technical expertise.

What are the security features of mPOS systems?

mPOS systems typically have a number of security features in place to protect cardholder data. These features include:

  • Encryption: All cardholder data is encrypted when it is transmitted between the mPOS system and the payment processor. This prevents hackers from intercepting the data and stealing it.
  • Tokenization: Cardholder data is tokenized before it is stored on the mPOS system. This means that the actual card number is never stored on the device, which makes it more difficult for hackers to steal.
  • Regular security updates: mPOS systems are regularly updated with the latest security patches. This helps to protect them from newly discovered vulnerabilities.

EMV Chip Technology: Guarding Against Card Fraud

One of the foremost security features of mPOS systems in the UK is the integration of EMV chip technology. EMV chips are designed to prevent counterfeit card fraud by generating unique transaction codes for each payment. This means that even if a hacker manages to intercept a transaction, the data will be useless for future transactions, significantly reducing the risk of fraud.

P2PE (Point-to-Point Encryption): Safeguarding Transactions

P2PE is a technology that encrypts payment card data from the moment it is captured by the card reader until it reaches the secure payment processor. This prevents hackers from intercepting sensitive information during the transaction process, ensuring that the entire payment journey remains secure.

Multi-factor Authentication: Adding an Extra Barrier

To ensure the legitimacy of users, mPOS systems often incorporate multi-factor authentication. This requires users to provide multiple forms of identification before accessing the system, making it significantly harder for unauthorized individuals to gain access.

Compliance with Industry Standards: Meeting Regulatory Requirements

mPOS systems in the UK adhere to stringent industry standards and regulations, such as the Payment Card Industry Data Security Standard (PCI DSS). Compliance with these standards ensures that businesses are implementing the necessary security measures to protect customer data and maintain trust.


As businesses increasingly embrace the convenience of mPOS systems, it’s crucial to prioritize security. The UK’s mPOS systems are equipped with state-of-the-art security features that guard against fraud, data breaches, and unauthorized access. From EMV chip technology to encryption, tokenization, and multi-factor authentication, these systems offer a comprehensive defense against evolving cyber threats. By choosing an mPOS solution that prioritizes security, businesses can enjoy the benefits of modern technology while keeping customer data and financial transactions safe from harm.
