What it means for the transaction

  • If the service code starts with 2 or 6 (chip card) and the terminal is chip-capable, a swipe is fallback; Visa flags this with the chip condition code in Field 60.
  • Counterfeit liability shifts to the party that did not support chip.
  • Typically sent as 901 or 902.

How 90 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.)
