RE: Smartcoins POS :: The free way for companies to accept crypto-currencies
I sound a bit biased when it comes to QR vs NFC. Just fyi, I do understand that most merchants are upgrading to NFC and our libraries support NFC yes, but I prefer QR codes personally, because of the security advantages. Many merchants are upgrading to tablet based systems which of course display QR codes nicely. Either way, we support them both right from the getgo.
