Well, I am not a high value customer compared to what other bank clients volume, but, yes if I have unauthorised transactions in my card, and I show them prove that they where not done by me, then yes they will reimburse and chargeback. Not sure if its because of the competition or if the banking law forces them to. Though banks in Panama regulate themselfs in a decentralized fashion.
What I say is in the context of French law. If you are billed a purchase that was unauthorized the bank *has* to refund you, you do not have to prove the transaction was not authorized. The rationale behind it is that if you did not input your PIN for a transaction the burden of proof is on the merchant, not on you.
What I'm trying to say is that your bank would probably have refunded you even without proof because (at least where I live) they are legally obliged to.
I think it stems from the fact that credit/debit cards are inherently insecure because you can pull money from them simply by knowing some digits, there is no authentication in the payment mechanism when you simply pay on the internet. I assume this legal obligation has been lobbied for by Visa/Mastercard because if it weren't so the insecurity of this payment scheme would be extremely obvious an no-one would want such a card.
Of course, I don't know anything about the laws in your country but I'd tend to assume they are somewhat similar in this respect.
I work with 3d secure, the thing about it is....... Ready? They protect the merchant not the buyer. The merchant is 100% covered when they use this it has nothing to do with the consumer.
From the consumer point of view it is much harder to reverse.
It is the merchants responsibility all the time, they have to prove you authorized the purchase.
Which is exactly what 3DS is for.
It is the merchants responsibility all the time, they have to prove you authorized the purchase.
Is there a sureshot way to prove that 3d secure was not used?
Yes, well actually it's the opposite, you can prove that the transaction authorization was done with 3DS.
Go to the site where the purchases where made, go all the way through the check out but do not pay. If the verified by visa or MC is displayed it was used. If not then you should win the chargeback.
You are correct for Visa, however, in MasterCard terminology it is called MasterCard SecureCode.
Keep in mind that the protection offered by 3DS varies with the country of the buyer. If you want to guarantee a payment, simply relying on 3DS is not sufficient.
