Paying Merchants with your Smartphone Name Ideas

We've got a new payments technology that allows customers to pay merchants via an NFC swipe and NFC smartphone. It's different to paypass and paywave, and although it's for payments, we'd rather stick away from the english word 'pay' - although if you can find a something really catchy with pay that's fine. Keep ideas include authentication, online, directory, service, fast payments, open ecosystem etc. Our system is simple, very very easy to us, really fast (lightening fast) and fun. We're looking for either a fun name or an acronym that is professional, as it will be place on terminals sitting in the merchants shop front. Something like Verifone or Ingenico could work. Avoid names already known, like 'mint'.
