DF62
Data Storage (DS) ODS InfoData Storage ODS Info is a single control byte describing the card's own on-device data-storage options within Kernel 2's data-storage feature - the card-side declaration that its sibling, DS ODS Term (DF63, covered alongside it here), answers from the terminal's side. Together the two form the same declare-and-supply pattern already seen repeatedly throughout this dictionary for other capability-and-content pairs: DF62 states what the card's storage supports, DF63 is the terminal-supplied value actually written into it. It's also related to the Requested Operator ID (9F5C, covered earlier), since which specific ODS Info options are even meaningful depends on which data-storage operator program is active for a given transaction. Because its exact bit-level content is scheme-specific rather than detailed in this entry, a terminal implementing on-device storage against DF62 needs the relevant scheme's own documentation to interpret it correctly, in the same pattern already established for the Terminal Risk Management Data (9F1D) and the protected/unprotected envelope families covered earlier. See EMV Contactless Book C-2.
