This tutorial focuses on P3 Card Edit Tool and its functionality.

P3 Card Edit Tool (BP-Cedit)

As its name states it is dedicated to EMV Card data validation and manipulation for issuers and card manufacturers. BP-CardEdit can read personalisation data produced by a Card Management System and also personalised data encrypted by the Thales P3 device. On top of this functionality it adds detailed information on contained EMV data and allows their convenient export in a text file.

Format & Data file loading

Files produced by a CMS mainframes or Thales P3 devices follow a layout defined in a fmt file. CardEdit will check if it has all available information for opening the data file and ask user to provide format file if not already loaded. Information from this file will be used for data file parsing.

Following information is then provided to a user:

  • Record ID & Header information
  • Record data statistics
  • Embossing information – plastic nr., valid from, valid to, cardholder name, company name, last four digits, cvv2 etc.
  • Magnetic stripe data – Track 1, Track 2, cardholder name
  • Carrier
  • Activation sticker
  • Chip data – separated by loaded applications, tags are visible in a tree view and can be sorted.

Card personalisation data usually follow proprietary format given by particular issuer. This may cause that not all data are read and parsed in a detail. Let us know if you are experiencing such an issue, our team will be glad to implement parser to match your data file.

Record management and data export

CardEdit allows limited record management on data loaded. This can be handled through a main menu and also through the navigation bar with list of loaded records. Particular records can be deleted and additional records loaded into a data set.

Export function located in Tools menu then allows to export all loaded data in a text file organised like on an example below. Such data can be then used for further analysis or easy manipulation outside of scope of CardEdit.
