I’ll 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. I personally believe it’s daunting to many programmers because the mechanism of talking to a smart card is something quite different from the higher-level programming we’re used to, which is one of the reasons why Thomas and I created.In this example I’ll 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. Almost all payment chip cards (except in France) uses a worldwide standard called (a rather meaningless acroynm from Europay-Mastercard-Visa, the founding members of the collaboration that created this standard though, ironically this US-created standard is used mostly outside of US).Retrieving information from an EMV compliant chip is not an inherently difficult task.
