“Currently, our users are placing the bridge at the reader side [just like a sticker], so that a mobile user can simply replace his SIM card,” he added. Um, if it only supports tag emulation mode, and it has to be placed on the reaader side like a sticker, then why not just buy a 13.56Mhz ISO14443 tag sticker?

I'm always in favor of the smarter way of doing things, but unfortunately "smarter" depends on whether you're the consumer or the manufacturer. Apple, as well as the wireless operators in the US which decide what hardware their customers can use, are certainly happier to mandate new hardware for the NFC bill-paying function. Much easier to get customers to shell out for the new hardware that way. Why give them the easy out of a chep update to their existing phones?

No, Quanray is using 13.56 MHz, instead of 2.4GHz.

Technically that may be OK but how about standardization ? Major Smartcard companies have focused on ISO14443 standard with 13.56MHz carrier wave. Moving to 2.4GHz may be a big issue.

Obviously, I am not suggesting RF-SIM to be used for iPhone. I am just saying it could have been an option for operators outside China, but they chose not to. In a country like China where phones are typicaly not offered by operators as a bundled service, RF-SIM is a reasonable solution.

RF-SIM wont work with the iphone as there is no microsim design. Also CMCC SH has stopped the RF-SIM service, according to 10086.

I totally agree with you, goafrit. It's a much more practical NFC approach, and it's easier to maintain compatibility as it offers tag-based only communication.

This is surely a better strategy. It makes NFC integration as well as ensure compatibiity.
