- Visa signals fallback differently: entry mode 90 with the chip condition code in Field 60.
How 80 appears in DE 22
In field 22 of ISO 8583:1987 and of the Visa and Mastercard formats, the first two digits are the PAN entry mode and the third is the terminal's PIN entry capability. EMV tag 9F39 carries only the two-digit entry mode. (ISO 8583:1993 replaced field 22 with a 12-character POS data code.)
