javaemvreader
It is an application written in Java. The project is hosted at http://code.google.com/p/javaemvreader/ and using the Apache License 2.0 licence.I have not yet tried to use the software. According to the web site the application is able to perform:
| EMV function name | Command |
| Initialize card | SELECT FILE "1PAY.SYS.DDF01" |
| READ RECORD (to read all records in the specified SFI) | |
| Application Selection | SELECT |
| Initiate Application Processing | GET PROCESSING OPTIONS |
| Read Application Data | READ RECORD (all records listed in the AFL) |
| (Read other application data) | GET DATA (ATC, Last online ATC, PIN Try Counter, Log Format) |
| Dynamic Data Authentication | INTERNAL AUTHENTICATE |
| Offline verification | VERIFY (only plaintext PIN verification is supported) |
| Read Transaction Log | GET DATA/READ RECORD |
| N/A | READ RECORD (brute force all valid SFI values and record numbers) |
The application uses the javax.smartcardio API to talk to PC/SC.

It is not an application but different web services to parse EMV data.| EMV tag search | Look up EMV tags in this handy database. Search by keyword e.g. for all tags that contain the word "currency" or "cryptogram" in the description, or look up a hex tag e.g "9F20". |
| TLV decoder | Decode EMV TLV (Tag, Length Value) byte strings into their constituent tags and sub-tags. Useful for analysing APDU traces, responses and so on. |
| CAP calculator | Generate CAP codes using an emulated banking card and CAP calculator, to test against real gadgets or for testing authentication servers. |
| Cryptogram calculator | Generate and verify EMV ARQC, ARPC and TC cryptograms, calculated using the vital parameters of the card, UDKs, ATC etc. |
| DES calculator | Encrypt and decrypt hex strings using DES and 3DES, using the basic modes of operation, ECB, CBC. |
| ASN1 decoder | Decode a binary file into an ASN1 dump using an online interface to Peter Gutmann's dumpasn1 tool |
| PIN translation tools | Encrypt, decrypt and translate ISO PINblocks between different encryption keys. PINs, PANs, padding... all sorts of fun! |
| Keyshare generation tools | Automatically generate test keys of various lengths, and split into components. KCVs are automatically provided for each component and the whole key. |
| Truecolour hex dump tool | This hex dump tool will create a multicoloured, annotated hex dump of the provided file, making it easy to spot strings, markers, and high and low entropy areas of the file. Very useful for when you don't have your favourite hex dump tool to hand. |
| Character set encoding conversion | Convert strings of text and hex between ASCII, ECBDIC and hex representations. Suprising how often you need one of these! |
| ePassport MRZ calculator | Generate passport Machine Readable Zones (MRZs) from biographical details including name, date of birth, and passport numbers, expiry dates etc. Randomly created identities can also be used. |
