For the unintiated, the status word (SW) returned (90 00) indicates success.

I personally believe its daunting to many programmers because the mechanism of talking to a smart card is something quite different from the higher-level programming were used to, which is one of the reasons why Thomas and I created.

In this example Ill break down a sample Jaccal script line-by-line in its raw APDU format to show exactly how information is retrieved from the chip card.

Ill show the script twice the first one in pure APDU, and the second, a higher-level Jaccal script using Jaccal APIs to do the job for you.

In this example, Ill be showing you snippets from the official EMV4.1 specification, which Ill mention in passing but not in details.

Free Java Emv Reader For Mac Pro What do you need Firstly youll need an EMV chip card.

Most probably this will be a credit card or a debit card with a chip on it.

The one Im using is a from Gemplus (now Gemalto), but almost any card reader that supports will do.

Card readers are mostly plug-and-play though if it needs drivers, it should come with the package.

Windows supports smart cards by default so you shouldnt need anything special.

Im assuming that youll have a bit of knowledge of smart cards and some knowledge, but dont worry if you dont, just drop me a note in the comments and Ill add it in.

ATRs can be used to determine the card technology used and the manufacturer that produced it.

Atr open; prints(atr); In Jaccal script, the command prints displays a string in the output.

If youre using Jaccal from the command line, the output is the console.

Output Power on ATR 3B 66 00 FF 4A 43 4F 50 32 30 A quick check with the maintained by Ludovic Rousseau shows that the card I used (UOB Platinum Visa Card) is likely to an IBM JCOP (JavaCard Open Platform) 30 chip card.

Select the PSE directory This example uses the PSE (Payment System Environment) selection method to query the chip card and determine which application in the EMV card.

Not all EMV cards support this application selection method since this method is optional in the EMV standard.

MChip applications (from Mastercard) mandatorily supports it while VIS (from Visa) leaves it optional.

This means that if you try this with a Mastercard this will always work but its a bet with a Visa card.

The PSE begins with a DDF given the name 1PAY.SYS.DDF01 prints(Step 1 Select 1PAY.SYS.DDF01 to get the PSE directory); cmd new ApduCmd(00A45031); cardresponse execute(cmd); prints(cardresponse); We start with creating an ApduCmd object initialized with this strange alphanumeric string.

Looking at it carefully we can split the string into two parts, the first is the command, and the second is the data.

The first part is a ISO7816 select command (00 A4 04 00 0E), while the rest is the hexamdecimal representation of the ASCII character 1PAY.SYS.DDF01.

Raw output The result shows a successful selection of PSE, which means that the PSE exists in the chip card.
