Dear Tran, Jonathan and all.

I basically agree with Tran's opinion.
Concerning API for contactless communication devices (NFC, RFID), I believe this API should be supported for web application.
Because RFID is quickly deployed in the industry and currently this is used as an identifier for connecting things in physical world(e.g. poster, product) to information/services of internet. In this context, various kind of valuable application could be implemented based on this API for mobile devices.

Best regards,
Wonsuk
