Other New Response Fields
In addition to print fields, other fields have also been added to the Simplify response to support EMV processing.
As shown in the following table, added fields provide the POS with information regarding e.g. data entry mode, terminal capabilities and chip condition.
|API Field||Field Name||Description|
|0047||POS Data Code||Defines properties of the POS device, PIN Pad capabilities or the cardholder interaction|
|0052||Transponder / Proximity Indicator||Value based on a combination of PIN Pad contactless capability, card data entry mode and type of contactless supported (if any)|
|0054||POS Entry Mode||Identifies how the card data was entered|
|0055||PIN Capabilities||Identifies whether the PIN Pad is capable of accepting PIN entry|
|0057||ICC Chip Condition Code||Identifies the condition of the ICC Chip / Account data source|
|1359||EMV CVM Verification Indicator||Field to indicate to the POS the cardholder verification methods. Valid values are:
0 - Failed CVM
1 - Signature required
2 - PIN required
3 - PIN and signature required
4 – Not determined. POS should request signature.
These fields will be sent to the POS for any transaction (EMV or not) in which an ICC is present. For more information, see “EMV Elavon Gateway API Request Changes” in the Fusebox EMV Integration Guide (Host Request).
New response fields may also be sent for purposes of data retention. EMV fields must be retained by the POS for subsequent transactions and chargeback purposes. For more information, see “EMV Data Retention by the POS” in the Fusebox EMV Integration Guide.
