What it means for the transaction
- Issuers cannot apply chip, magstripe or keyed risk rules, so many treat it as higher risk.
- Networks expect a real entry mode; 00 in a card-present transaction is a common certification finding.
How 00 appears in DE 22
In ISO 8583 field 22 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.
