In last decade, I have been swiping cards on the portable EDC machines, carried by Pizza Guy or even my Milk Supply person. They have had this machine for almost a decade and I "trust" this machine for it's form factor, apparant secured looks and ease of
use.
Dongle connected to a mobile set, while offers 'Mobile' PoS; it rather creates more avenues of frauds, identity thefts than it solves any problem. I would not be comfortable if someone says that s/he would swipe my card on a dongle, which is connected to
her/his personal mobile handset.
I am curious to understand what is the argument for anyone to invest in an obsolete problem of mPoS...!! What problem are they trying to solve, which already does not have a solution...?
