Key

MandatoryMust be configured for EMV certification

OptionalConfigurable if supported by the terminal

ConditionalRequired only in specific scenarios (e.g. transit)

TAC values (rows with tag —) are non-TLV terminal parameters stored in the terminal's AID configuration file, not in a standard BER-TLV record. Example values are commonly cited scheme defaults — always verify against the current scheme Terminal Integration Guide before certification.

DF8xxx tags are proprietary contactless kernel tags. DF8117–DF811F are formally defined in EMVCo Book C-2 (Mastercard Kernel 2). Other kernels define the same logical parameters (floor limit, CVM required limit, transaction limit) but may assign different proprietary tag IDs in specific terminal SDK implementations — consult your terminal vendor's kernel integration guide.

Limit amounts in DF8xxx tags are 6-digit BCD in minor currency units. Example: 000000002500 = 25.00 USD.
