Ingenico introduces mPOS dongle for mobile wallet transactions

Interesting concept. I'm not sure how inspired consumers or businesses will feel having contactless card details being broadcast from a phone on purpose to another phone. Its a tough sell security wise if nothing else...let alone where is the value add for a business and or a consumer? 

Does this introduce any new security concerns? Or is it just a case of combining existing concerns around NFC and around mPOS?

Is it missing capability for chip cards?

Not exactly a discrete dongle!  But it does have contactless capability, which means any transaction above the Issuer nominated threshold and then you'd enter a PIN.

With regards to Matt Collins' question about if this solution adds security issues the answer is probably no. There are a few existing already and that has to do with mobile devices and mobile apps. With the rise of mobile malware and mobile hacker tools one should expect app providers to protect their apps, but very few are capable of doing it.
