I have been using the NFC equipment for few months before giving up on it totally. Firstly the handset's volume was so soft, I could hardly hear what the other party was trying to converse. Secondly, it tends to hang and kind of embarrassing when I tried many times in vain trying to tap on the EZ-Link reader of buses while other passengers look on. Thirdly, the battery went flat in less than 24 hours resulting in the EZ-Link feature unable to function.

However, I must say it definitely look cool having one of this equipment, at least using it the very first timein the public.
