|SumUp users a plug-in card reader
and ios / Android app to take card
payments via mobile phone
The principle is sound for a number of reasons, not least because it makes it easy for small merchants to start accepting card payments. But the bigger issue for the sector is over the supported technology - currently the mobile POS solutions are favouring a "signature" with the user running their finger on the smart phone screen.
However, since 2004 Chip and PIN has been compulsory in the UK and Ireland and as yet, while the plug-in card readers can read the card chip, they do not support the secure PIN verification. iZettle have recently got into trouble with Visa as a result of their authentication and so a more long winded approach has been devised, which is less user friendly and will thus undoubtedly slow the practical adoption.
Anyway - this technical hurdle is surely only a blip. We're sure there will be many further advances in mobile POS to come and expect we'll be involved ourselves in some way. More details on that in the future.
