"this almost suggests that people trust LINE more than the credit card processing infrastructure"
And to think that until recently LINE used to send things unencrypted over plaintext when using mobile internet.

When we first got here, my wife couldn't pay our phone+internet bill (using the third largest telecom in the country) online, because they need to whitelist card numbers on accounts because of fraud (or so we were told).
When we tried it once with my (then) Australian Visa card, it failed miserably and the app dumped out a PHP stack trace in its web view with a SCARY amount of information exposed to me.
Even things like using a banks' "Pay Bill" feature is apparently not reliable here, because payments somehow don't turn up in a timely fashion or they don't know they've arrived or something.
People do what they're comfortable with and what they know - just like how staff always ask for a signature on the bottom of a credit card slip that clearly says "signature not required" because I used a PIN.
