Project Description

One of the first contactless payment solutions in the UK and the first mandated for use on Transport for London

  • Pioneering contactless payment technology in the UK
  • EE, UK’s largest mobile network operator, needed a partner with long experience in Near Field Communication (NFC)
  • Simple and intuitive for the end-user, while maintaining high security
  • Complex project, multiple stakeholders
“This complex project involved numerous stakeholders and therefore to ensure the project ran smoothly and to deadline, Penrillian’s team attended regular stakeholder meetings and were in regular contact with all parties involved. We were therefore able to navigate the complexity and deliver a completely successful end product.”
Charles Weir, Penrillian


EE, the largest mobile network operator in the UK, wanted to launch a mass-market contactless payment application involving multiple stakeholders.

Priding itself on innovation, EE chose to work with Penrillian on this project because we are a company that could develop a secure mobile payment solution using NFC-enabled mobile phones. EE needed a partner that had the right skills for this complex project, in particular with NFC technology.

Penrillian created one of the first payment solutions using NFC in the UK payment industry and prepaid market.

The Challenge

Working in partnership with EE, PrePay Solutions and Oberthur Technologies, Penrillian’s role was to build an NFC mobile payment application that was simple and easy to use for the end user – despite being complex to develop thanks to its high levels of security.

Penrillian also had to develop, host and manage a companion web application that was highly responsive, and put the new EE brand front and centre.


Penrillian delivered an application that incorporated account management and contactless payments. Cash on Tap allows users to pay for goods up to the value of £20 using their mobile phone without the need to enter a PIN.

This was the first mobile contactless payment system to be mandated for use on the Transport for London network.

Penrillian delivered on time and to budget and, following the initial success, continued to work with EE on new and exciting features for the next phase of the application.
