CHIP PIN

[anhlong]

Visa Electron application
and in the data of the chip equivalent track for some reason, the Citibank master card: "5466164353502137D19072011720300000727F"
but it is not important
This card cannot be recorded as an SDA card and used in a terminal that only supports SDA authentication.
in the past, with improper personalization of cards in banks,
there was an opportunity to write an SDA / DDA card as a card supporting only SDA and use it in a terminal that supports the authentication method only SDA (old terminal)
The above transaction took place using dynamic authentication. The card has a data object in which the transaction processing profile is included. This profile is submitted for signature.
This is done against cloning. even if this card supports both dynamic and static authentication, it will not work on a new card,
because it is necessary to change the transaction processing profile which is specifically protected on this card by inserting it into a special data object.
if this were not, it would be possible to create a new card, but exclude support for dynamic authentication in it, leaving only static. but you can't do that on this map.
and for cloning a dynamic map, creating a dynamic clone, there is no way to get a random number. which is used with every new transaction.
a random number was used in this transaction.
