Search and decode the complete EMV tag dictionary. Each tag identifies a specific data element in EMV chip transactions — the PAN, cardholder name, application cryptogram (ARQC), terminal capabilities, and hundreds more. Look up any tag by hex number or name to decode what a card or terminal sent; pair it with the TLV Parser to decode a full response tree.
