FIND the PIN EMV #100
Comments
hi Valerii,
thanks for the reply, well i have been able to test and validate the chip
pin using the cardpeek with the script code to request the pin
verification. and even if the computer was offline, the cardpeek software
was able to tell when my pin entered was wrong and when it was the right
one.which clearly indicate that the offline pin is in the chip card, and in
that same moment, the pin that cardpeek verified was the actual offline and
online pin, since it was the same one.
would you be able to recreate that scenario but to find a way to read the
pin, without previously enter it.
thank you for your time.

… Usually PIN is not checked by tye card. It is checked by issuer bank (most
operations are online operations with online PIN check). For online
operations with offline pin check you need to first initiate transcation
from bank. For offline transactions it is more complicated.

The PIN is not readable on EMV cards. When an offline pin check is required, the PIN is sent to the card and the card answers YES/NO if the pin is good or not. The PIN is stored in an unreadable area of the card and never leaves the card. |
thank you for both reply, since people was saying that the pin was not in
the card, then with test, i was able to proof that the pin was in the card,
then people said that its not the online pin but only the offline pin, then
again with test i was able to proof that most of the time both pin are the
same, so which mean offline pin is on the card. by asking the chip if the
number entered are the good number. but most of the card information are
avaible to be readable. so my guess would had been, that the chip do an
calculation of different variant, but always placed at the same place, then
said to the machine, yes i have the same calcul result or no i dont have
the same calculation result. it was more that everytime i was trying to
stop work on this enigma, a new information backed with test, was
motivating me to keep trying.
thank you for time guys

Lol, that does not work for modern cards with DDA or CDA.
in an unreadable area of the card
Yep.

the technology change and update every day, but the feeling of been able to
beat those security measure, show us that everything is possible.

Here in my bank you can update you pin in the app on you smartphone and
then on next operation the offline pin will be updated!
Also, there exists CDCVM, like Apple pay, Google Pay and Samsung Pay. They
are not using pin at all! They use your biometrics (on smartphone, iris,
fingerprints or face id). The amount of money is also shown on your
smartphone. That is nice, is not it))

Hey where can I find #71 one script |
my card has blocked the password due to too many attempts, I have the pin, is there a script for me to unlock my card or reset the number of attempts? |
The fact that the PIN is stored on the card doesn't mean that it's possible to read it. Smart cards, including EMV payment cards, aren't simple memory devices that can be freely read/written. They are more akin to lightweight computers, with their own processor, storage, programming, etc. and when using a smart card you're using the interface that the application running on the card exposes, and only the operations made available are possible. The EMV application doesn't allow the PIN to be read, only verified, and while there may be mechanisms for changing the PIN they generally require further authentication. |
what about offline payments that ask for pin? is that even a thing? I'm aware not all payments go through the issuer network |
Yes, in that scenario the reader is passing the PIN to the card, and the card verifies it internally. Assuming it’s correct, it will proceed to authenticate the transaction. It doesn’t provide any other information other than whether or not the PIN provided was correct, and often after several incorrect PIN attempts it will lock out. |
how can we pull out the Pin, since the Pin its in the card, who know how to pull it out.
