Identify the serial number (UID) returned by a project card

  1. Connect the reader to your computer.

    I have an Ethernet reader.

    To work with BALTECH tools, an Ethernet reader must be unconfigured, or required permissions must be granted in PKI Authentication and Encryption settings.

  2. Open BALTECH ID-engine Explorer.
    If you haven't installed it yet, you can download it here as part of BALTECH ToolSuite.

  3. At the top left, click Analyze Sample Card.

  4. Place the card on the reader.
    The card will be displayed including its UID. The UID in decimal format is the number you're looking for.

ISO 14443 Type A UIDs are returned differently by certain non-BALTECH readers

BALTECH readers rotate these UIDs bytewise by default, i.e. the first byte is swapped with the last, the second byte with the second-last, etc. Certain non-BALTECH readers don't do this.

For compatibility with such readers, create a configuration containing an Autoread UID component for your card type and enable the checkbox Rotate Bytewise.
