Android Developer

The Role

The primary purpose and scope of the Android Developer is to help develop and support existing MYPINPAD products. Working with the Android Development Team, Services Development Team and UX Team, the Android Developer will be a passionate app developer who enjoys a technical challenge.

Background and context

PIN on Mobile is a transformative technology, which will lead to a massive expansion in mobile acceptance devices. Point-of-sale terminals and PIN entry mPOS devices will be replaced by everyday smartphones and tablets running secure payment software. This has only been made possible by the card scheme security council (PCI) publishing a new standard on how PIN can be securely captured by a smartphone or tablet. This new standard is known as Software-based PIN Entry on COTS (Commercial Off The Shelf); SPoC, or also known as PIN on Mobile.

MYPINPAD is industry recognised as one of the leading experts in this extremely complex field having invested over 6 years and millions of pounds in defining, developing, and enabling PIN entry capability on a smartphone or tablet. Utilising a standard PIN pad image (not scrambled), ensures seamless customer adoption, while in-built support for the visually impaired delivers a fully inclusive solution.

A number of key industry partnerships have been forged and contracts have been signed to deploy this cutting edge technology across the globe.

The market opportunity is huge with the card scheme predicting market growth to be in the region of 300 million acceptance points in the next 5 years.
