Hello everyone. I have some time since I am trying all types of EMV softwares, unsuccessfully! Any opinions about this : “As part of the information exchange between the card and the terminal there are several data fields that are of particular interest to a fraudster – most notably Tag 57 (Track 2 Equivalent data). Contrary to popular opinion this data is not an exact copy of the magnetic stripe track 2 data. For example in the genuine magnetic stripe an equals sign (=) is used as a field separator but in the Tag 57 Track 2 equivalent data this is replaced with an alpha character (D). Additionally in the genuine magnetic stripe there is a Card Verification Value (CVV) encoded in the Issuer Discretionary Data – in the Tag 57 equivalent this is replaced with an Integrated Circuit Card Verification Value (iCVV). Although the CVV and iCVV share the same Cryptographic Key – they use very different seed data which guarantees them to be generated as different values. If implemented correctly an Issuer Authorisation host ‘should’ detect if someone has skimmed Tag 57 data and constructed a fake Magnetic Stripe with the iCVV instead of the CVV (they might be smart enough the change the D to an = but unless they have copied the magstripe they will have the wrong cryptographic check value). In cases where this is detected by the Issuer Authorisation host it is recommended that you suspend/block the card and contact the genuine cardholder to arrange card replacement as it is suspected their card has been compromised.
I know that it’s a long discussion about this subject but I really need to know if this really work? Has anyone succeeded? I have followed all the steps , used the right equipment, fresh dumps with pin ( 100% freshly harvested) , nearly 400 and NOTHING, absolutely nothing!! Card invalid !!
