#Read emv card code#
The EMV chip provides a unique transaction code unlike the traditional cards that can be replicated for counterfeit transactions. EMV chips will not prevent all forms of security breaches, but will decrease the amount of fraudulent activity from stolen debit card data.Īll Members Exchange credit cards currently come with chip technology. Personalization process is much more complex.An EMV chip is a small, metallic square that replaces the traditional magnetic strip cards. You should check EMV CPS (Common Personalization Specification) and GlobalPlatorm specifications. To encode data to different card - it is completely different story.

To work with ICCs it is essential to understand a difference between these protocols.Įach step above starts from APDU name to make you easier find information into EMV Books 1 and 3.
#Read emv card verification#
ICC uses PIN only inside using VERIFY command, and ICC just returns PIN verification result and PIN try counter if PIN was wrong.ĮMV Book 1,also, describes 2 used data transmission protocols, T=0 and T=1. You will be unable to read PIN from card, PIN is personalized in records, which are not available to read from outside. Just run over AFL and read records from every SFI from first to last records, that is all (consult book 3 for more information). It contains 4 byte long information on every file with records to be read during transaction. AFL is constructed from several parts: containing information about file (SFI - Short File Identifier), first record number, last record number and count of records used in Signed Data Authentication: 1st byte - SFIĤth byte - Count of records in file to be used in Signing Data Authentication This APDU increments ATC (Application Transaction Counter) and returns AUC (Application Usage Control) and AFL (Application File Locator), which must be used to read data you need (Check EMV Book 3 for info).Ĥ) READ APPLICATION DATA - using AFL returned in 3) you can read Application data. It will return FCI (File Control Information) of Application file and make Application SELECTED on ICC itself (Check EMV Book 1 for more information).ģ) GET PROCESSING OPTIONS - initiate transaction on ICC. AIDs of Visa and MasterCard: A0000000041010 - MasterCard This is optional step, you can start from step 2) and try to select both Visa and MasterCard AIDs to check which of them is available on ICC.Ģ) SELECT application which you want to run using correct AID from list you have got in step 1). DFs are named by AID (Application ID), which you will use to create a list of available applications (candidate list) for selection, if you want it, or just find AID with the most less Application Priority Indicator (check EMV Book 1 for more information). The sequence of APDUs to read application data is the following:ġ) SELECT PSE (Payment System Environment file), it contains a list of Application DFs installed on smart card. You are interested in 1st and 3rd books to read application.

Specification is splitted into 4 parts (4 books).
#Read emv card how to#
You must check EMV ICC card specifications to understand, how to read data from ICC, specifications are freely available to download. If card runs T=0 protocol, in response to each APDU which assumes R-APDU (Response APDU) to contain Data field, card will return byte count ready to be read and you should issue GET RESPONSE commands which is described in Book 1 of EMV specification. usually is located in records which are set to be used in Sighed Data Authentication in AFL. PAN, expiry, effective date, track 2 equivalent data, etc. TC - 80A8000002830000 # check if PDOL presents on card, if not, only 8300 should be added to DATA filed of APDU
