Japanese social network Mixi introduces NFC check-ins

Leading Japanese social network Mixi, which has more than 21 million members, has become the first social network to offer users the ability to check into locations using near field communication. The service is compatible with Android NFC phones such as the Google Nexus S and uses Taglet, a Japanese language NFC tag reader and information sharing app launched last month.

Few details of the service have been released so far, but Mixi clearly envisages members being able to use the service to both check in at particular locations and to receive rewards.
