Tell me ur CC no and CVV number then u know.

For research purpose..im gonna need ur card number, CVV and expiry date..

I think you only need CC no, as I tried it before, I simply key in CVV also can pass? The bank will send OTP to phone, but then once I enter OTP correctly, payment still can be make online. (Note: I simply key in wrong CVV)

Tell me yours, I'm also doing research for my PHD now.

Interesting..... Can did the payment actually went through? Wrong CVV but correct OTP?

wrong CVV still can approve payment

please give info which bank credit card is that, I gonna ban it.

4456 6745 3245

346

04/21

Yes, I tried many times already...Just put in CVV as 123, 234 as what I tried before...I'm not sure if all bank like this. Maybe you can test it and share with us

My research didn't allow for 12 digit card no. only

how many digits u want?

If u key in CVV then there's no need for PAC/TAC code already.

CVV is for bangla to research

I have a thought that CVV nowadays is obsolete. Last 20 years it is vital as a security precaution that you must have a card physically with you when doing online transaction, therefore CVV was required. Last time your full 16 digits credit card number was not encrypted/masked on your purchase receipts. You can spend your time at petrol station dustbins and gather a lot of credit card numbers and use it to do internet purchase. Many credit card gateway providers didn't require CVV during that time and online fraud was rampant. It was so bad that Malaysia was among the list of highest-risk fraud country.

Now with the emergence of OTP, it provides an extra layer of protection. It doesn't matter if you have a physical access to the card. Without valid OTP your transaction will be rejected.

I think this one depends on the merchant and banks themselves? For eg: TM Online website, even if I key in the correct CVV, it will still go to the next page for me to key in the OTP.

Wah...share which bank...

Give me your card full number, expiry and CVV number.

I'll show you how important it is.

confirm stolen credit card which is closed.

Arrest him

when you do your purchasing/billing online, you are required to enter the CVV number before you are allowed to make payment.

your card number doesn't change when you replace your card, your CVV will.

hmm wat?

i just made those numbers up...

actually it is depend on merchant how extensive they want to verify the cc.

they may choose to verify other details like address, postcode and etc also.

if they don't they will bear the liability if there is fraud.

to verify credit card holder ...

use only in online trx that shows you are holding actual cc

you see my smiley? Just kidding la

tis

TS is a fucking bullshit

ohh..

I think maybe is Merchant problem? I tested it to pay TM bills via TM Online Portal...

Otp will send. But will reject after u key in otp.
Tried many time before.

your CVV is your promo code

please key in everytime you purchase something online

if its 103 then you get 10.3% discount

if its 426 then you get 42.6% discount

May I know which bank and which merchant that can reject?

Seriously? How? Lol

I think all will reject if the ccv is wrong.
I used cimb/pbb, you try next time when buying movie ticket lo.
U need key in the correct otp received. Then when processing it reject.
