enable NFC and scan your IC (use back cover scan)
and hear whether got beep sound or not

no need app, just scan only
if heard beep sound then can already

try hear got any sound or not
the sound very low, put the speaker near to your ear

Touch 'n' Go card

llk told you already
that why I said normally use not original battery NFC won't work
original battery off course working

How actually how long the S3 battery life can last for normal use? I charge full yesterday night then went to sleep but morning when I checked I show left 70%. Wifi is off. how to check any background application is running.

Thanks
