Over the weekend, Verifone introduced a new operating system and device that retailers could use for mobile payment. It's an independent mobile point of sale (mPOS) payment terminal that receives mobile payment whether from a smartphone or a tablet. Officially called as PAYware Mobile e355, this newest Verifone mPOS terminal eliminates the need to frequent upgrading of both the mPOS terminal and the OS. This one comes with a special OS that can be tweaked, which means any merchant can customize and update the system as needed. No need to change the hardware at all since all it needs are some updates on the operating system.
