Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

How to use pyGlobalPlatform to GET DATA from the card

Post by JavaCardOS » Tue Nov 24, 2015 7:36 am

The Issuer Security Domain(ISD) stores the following data:
• Issuer Identification Number (IIN)
• Card Image Number (CIN)
• Card Recognition Data
• Issuer Security Domain key information
• Other Card Issuer's proprietary data

These Card Data can be retrieved using the GET DATA command.

Here is the code which shows how to use pyGlobalPlatform to get data from card.

Code: Select all

# Import the module
import globalplatformlib as gp

# Establish context
context = gp.establishContext()

# Select smartcard reader
readernames = gp.listReaders(context)
readerName=readernames[0]

# Connect the reader
cardInfo = gp.connectCard(context, readerName, gp.SCARD_PROTOCOL_Tx)

# Get SCP details
scp, scpi = gp.getSCPDetails(context, cardInfo)

# Mutual Authentication
securityInfo = gp.mutualAuthentication(context, cardInfo, gp.DEFAULT_KEY, gp.DEFAULT_KEY, gp.DEFAULT_KEY, gp.DEFAULT_KEY, 0, 0, scp, scpi, 0, 0)

# Get data from card
data1 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_IIN)
data2 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_CIN)
data3 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_CARD_DATA)
data4 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_KEY_INFORMATION_TEMPLATE)
# Optional
data5 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_SECURITY_LEVEL)
# Optional
data6 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_APPLICATIONS)
# Optional
data7 = gp.getData(context, cardInfo, securityInfo, gp.TAG_DATA_EXTENDED_CARD_RESOURCE_INFORMATION)
# Optional
data8 = gp.getData(context, cardInfo, securityInfo, gp.TAG_CONFIRMATION_COUNTER)
data9 = gp.getData(context, cardInfo, securityInfo, gp.TAG_SEQUENCE_COUNTER)

# Release context
gp.releaseContext(context)

# Print the card information
if data1 != -1:
    print "1 IIN: " + "".join("%02X" %(ord(b)) for b in data1)
if data2 != -1:
    print "2 CIN: " + "".join("%02X" %(ord(b)) for b in data2)
if data3 != -1:
    print "3 CARD DATA: " + "".join("%02X" %(ord(b)) for b in data3)
if data4 != -1:
    print "4 KEY INFORMATION TEMPLATE: " + "".join("%02X" %(ord(b)) for b in data4)
if data5 != -1:
    print "5 SECURITY LEVEL: " + "".join("%02X" %(ord(b)) for b in data5)
if data6 != -1:
    print "6 APPLICATIONS: " + "".join("%02X" %(ord(b)) for b in data6)
if data7 != -1:
    print "7 EXTENDED CARD RESOURCE INFORMATION: " + "".join("%02X" %(ord(b)) for b in data7)
if data8 != -1:
    print "8 CONFIRMATION COUNTER: " + "".join("%02X" %(ord(b)) for b in data8)
if data9 != -1:
    print "9 SEQUENCE COUNTER: " + "".join("%02X" %(ord(b)) for b in data9)

hello,
I select all codes about this topic, and paste it into my python script.
There was an error when I run the python script, and it prompt "python.exe stopped working".

This is why? Can anyone help me ?
