问题 What is the relationship between the EMV ODA , CA and issuer certificate during the transaction? 回答1: Offline data authentication is the process to verify the cards authenticity. Terminals are loaded with CA Public key. SDA(Static Data Authentication) can assure you the card data has not been altered after the issuance. SDA card contains Signed Static Application Data and Issuer Public Key certificate. CA Public key in the terminal is used to verify the Issuer Public key certificate and

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 months ago . I am trying to build an application to read/encode data on Cards, information like PAN, expiry, customer name, PIN etc, So far I could figure out that I need to send APDU commands to read data from Card but there seems to be no clear documentation available as to what commands

问题 I have few questions when the reader initiates the transaction with NFC emulated payment application using HCE Does the reader send the PPSE command as with the regular contactless card infrastructure? Does the host controller respond to PPSE command with the list of AID's from the registered AIDs listed in the routing table? So after the reader selects the AID, the host controller directs to the right HCE service? Please correct my understanding on the above concept. 回答1: An EMV payment card

问题 I need to read account number from Maestro/Mastercard with smart card reader. I am using Java 1.6 and its javax.smartcardio package. I need to send APDU command which will ask EMV application stored on card's chip for PAN number. Problem is, I cannot find regular byte array to construct APDU command which will return needed data anywhere... 回答1: You shouldn't need to wrap the APDU further. The API layer should take care of that. It looks like the 0x6D00 response just means that the

问题 In the EMV protocol the IMK(ac) is used to generate the session key, which is used to generate an ARQC. The IMK(ac) is exclusive to the chip and the card issuer host As far as I understand, the card issuers do not share those keys with the card brand (i.e. Visa cannot validate your ARQC, only "The Bank of Peoria" who issued the card can). When an EMV Apple Pay transaction occurs in which the phone generates the ARQC, which IMK(ac) key is it using? Presumably it can't be the IMK(ac) from the
