Mobile payment is still a bit of a wild west at the moment, and seemingly every technological and financial institution has a dog in this fight. Bank of America's not going to just sit idly by and watch it all unfold. The US's second largest bank has flirted with NFC in the past and is currently doing trials with QR scanning in Charlotte, North Carolina, where it's based. At present, five sellers in the area are taking part in the pilot program, with bank employees given access to the technology. The three-month trial is the result of a partnership with mobile payment company Paydiant, is compatible with Android handsets and iPhones, no NFC needed, naturally.
