It looks like a mobile phone inside of a calculator (and that may be just about what it actually is). Regardless, Movilway, a payments platform serving the underbanked mostly in South and Central America, are further developing their self contained cellular POS system. It works mano-a-mano with their pre-paid system for money transfer in order to facilitate payments sans bank account or credit card. Think of it as being like a combination of paypal and western union, in that you go to physical merchant locations to deposit cash into the system, but then can carry that credit indefinitely inside the system and debit it anytime you want at select Movilway merchants. Their goal is to further deploy and make non-cash payments possible in developing markets where having a bank account or credit card may not be an option due to lack of infrastructure.
