Field 55: ICC Data

Format: LLLVARb…999

Description: Field 55 is used to transport ICC data. This data element utilises the Tag, Length, Value (TLV) structure to delineate different sub-elements in the following manner:

<LLL><TAG><LENGTH><VALUE><TAG><LENGTH><VALUE> ………

Tag
Length
PDS Data

b ..2

b 1

b ..127

  • LLL: This describes the aggregate length of the data in data element 55.

  • TAG: Contains the tag identifying the EMV data object transported in this PDS (e.g. PDS “9F26” corresponds to the EMV tag “9F26”). The PDS Tag consists of either one or two bytes, represented as hexadecimal. The second byte is provided only if the continuation indicator in the first bye is set. Refer to the EMV 98 Specifications for the structure and definition of the EMV tags and definition of the continuation indicator.

  • LENGTH: Specifies the length (in bytes) of the PDS data, expressed as a binary number in the range 1 to 127.

  • VALUE: Contains the actual data from the corresponding EMV data object, as identified by the PDS Tag.

    PDS’s can appear in any order in Field 55.

    If DCC is accepted by the cardholder at POS, DCC amount and DCC currency code are used to generate cryptograms. In the case of zero decimal place currencies (e.g. Japanese Yen), follow the example below:

    Where Field 6 (Cardholder Billing Amount) = 1000 (10 Yen) use the value 10 to generate the cryptogram.
