AID list (aidlist.json)

This file acts as a database of ISO/IEC 7816 application identifiers (AIDs) and their human-readable metadata.

It is used by commands that try known app selections and then print decoded information (for example hf 14a info --aidsearch, hf 14b info --aidsearch, etc.).

Format

Each entry in client/resources/aidlist.json must contain all of the fields below (use an empty string if data is unknown):

• AID: Application Identifier as a hex string, no spaces or separators, representing raw bytes in ISO7816 select order (big-endian byte order as transmitted in APDU data).
• Vendor: Organization, scheme, ecosystem owner, or issuer most directly associated with this AID. Specify multiple issuers with a comma or semicolon separator.
• Country: Primary country associated with the vendor or deployment context. Leave empty when unknown or globally used.
• Name: Short user-facing application name.
• Description: Extra context, disambiguation, references, legacy naming, known usage notes, or deployment-specific remarks.
• Type: High-level category tag (for example transport, emv, gp, pacs, ndef).

Optional fields

• ResponseRegex: Case-insensitive regex matched against the APDU SELECT response encoded as hex without separators. Current regex subset supports ^, $, ., *, and \ escape. Use this field when multiple protocols share the same AID and can be distinguished by response content.
• Sources: Array of strings describing where the AID metadata was sourced from. Supported formats:
  • android://<package.name> for Android apps that declare or use this AID.
  • http://... or https://... for public references used to add or verify the entry.
