Hey all sifus, thanks so much for all the info shared, really great.

I've got a quick question, why don't the banks in our country use PINs instead of signature to verify credit card transactions. Or is there an option to do so?

Would be much safer right cos fraudsters can't guess your pin that easily (unless you're an idiot who uses 1111 or 1234). Also seems much more convenient than a signature, at least faster. I've been studying in Australia and it's been mandatory since earlier this year I think.

Do you think it would be helpful? I know so many people who've been defrauded before and cashiers nowadays don't even look at signatures so I think PINs make sense. 

yea.. thats why i feel i am stupid..
so if i call him to cancel.. he shud be cancel right?
no case like.. he would ignore and just pass my form up?
just worry bout this vry muchhh~~ ><
