Korea Times: Hyundai Dept. Store to Launch Mobile Payment Service

Based upon the carriers listed as offering the service (KTF and LG Telecom), this appears to be a Brew application.

Yang said that customers will need a Kookmin Card service and to download the mobile payment settlement program from Kookmin Card's website onto their handsets in order to use the service. Only KTF (016 and 018) and LG Telecom (019) mobile service users will be able to utilize the service. ... Customers will be able to settle payments by pointing their phones at the point-of-sale (POS) device at the sales counter and pressing their password into the phone's keypad, just as they do when they switch TV channels with remote controller. Then the money will be charged to their credit card.

I'm interested in learning more about this -- if you have more information on this offering, please email me.
