Carrier roaming NFC agreements

Reading Time: < 1 minute

NTT DOCOMO have announced that they will be attending CommunicAsia in Singapore (June 21 – 24) and a couple of things that they will be showing off caught my eye. First of all NTT DOCOMO are pushing the boundaries on technology to try and ensure that we can have world phones that support existing and next generation networks – they will be showing off a six-band prototype amplifier.

Probably of more interest was the idea of roaming mobile payments via NFC. NTT DOCOMO already signed a deal to make this happen with KT (Korea Telecom). The question that crossed my mind was did telecoms carriers have the processing capability that credit card processors like MasterCard, Visa and American Express? I don’t think that the current systems for roaming charges would be sufficiently swift and optimised for the wide range payment values.
