I would like to better understand the mechanism of rotation of EMV keys used for payment cards.
Assuming that it intends to provide a rotation of the keys used for the production cards:
just recycle the keys under Master Key and get a new… Continue reading Rotate or replace EMV keys?
The (EMV) Protokol that means in germany or other european countries they using 206 correct?
206 Internationale Chipkarte
Normale Autorisierungsverarbeitung
Das Terminal muss zur PIN-Eingabe auffordern, wenn ein PIN-Pad vorhanden ist
I wanted to ask if it’s possible to clone your own credit card (clone the emv chip) and copy it onto another emv chip with an emv reader/writer.
Shouldn’t this be easily possible without extracting any private keys whatsoever? Since I just… Continue reading Clone a credit card [duplicate]
I’m doing a project on the Apple Pay bug which has been in the news lately.
Apple Pay Bug
I want to program a simulation in Java, which would simulate the entire bug using software alone.
The EMV standards have three ‘layers’ for a transac… Continue reading Simulating Contactless Apple Pay Transport Payments in Java
If a credit card or debit card has a emv chip can it be successfully cloned onto a credit or debit card that does not possess a emv chip
If so how does that work and will the ATM accept it
I’m a newbie in emv world.
I’m trying to follow this flow:
I’m in the third step. I have to manage the Offline Data Authentication.
How can I negotiate the correct way (SDA, DDA or CDA) with the ICC to perform offline auth?

I was wondering how to make (or buy) custom passive NFC-enabled kernel cards similar to EMV Payment cards.
I want to implement an own EMV-like communication algorithm to verify the authenticity of the NFC tag data using signature calculati… Continue reading Custom Kernel EMV-like NFC Cards [closed]
Quoting from EMV Book 1:
This contact is used as an input (reception mode) to receive data from the terminal or as an output (transmission mode) to transmit data to the terminal. During operation, the ICC and the terminal shall not both b… Continue reading When does a card switch to transmission mode, and can it be done forcefully?
ISO 7816 smartcards are typically used in EMV transactions. I know that the card can perform arbitrary actions before sending a response to the terminal in a typical EMV transaction (e.g. signing dynamic data to generate SDAD). However, is… Continue reading Can ISO 7816 (EMV) based smart card handle interrupts?
I am looking into EMV Contact and Contactless protocols, but I felt there were a few ambiguities which I would appreciate help with:
Is the chip used in EMV Contactless capable of performing the same computations as the contact? I know th… Continue reading Are there any transaction time constraints in EMV contact and contactless cards?
