EMV Tag Lookup

Type a tag in hex (e.g. 9F02) or a fragment of its name (e.g. 'amount') and get the canonical EMV Book 3 / Book 4 description, format and source. Pairs with the EMV TLV Decoder. Runs entirely in your browser.

Tag (hex) or name fragmentHex tags are matched exactly first, then as a prefix. Otherwise the name and description are searched.
