Agnos Visa C3 v2.x
The list of options presented presented here reflects the qualification reference used at Amadis to test Agnos kernels with appropriate tools (EVAL or ICC Solutions). It doesn't reflect TA requirements nor most up-to-date optional/mantory features released by payment networks. Please refer to your lab to validate your ICS before any debug or TA.
The VISA checksum is calculated dynamically versus the ICS. A specific tag 0xDF1A is used to set the TTQ. It must be added and updated in all combinations in “Other TLV(s)” section (ENTRYPOINT tab) with the TTQ ICS value.
This reference ICS doesn't document Visa values to be set (i.e., customers requirements) but Agnos supported values and how to set them in regards with any potential MSD/qVSDC ICS.

ICS VISA Checksum Calculation
1) Preliminary
A unique checksum must be set in the VISA ICS and retrieved using a test tool such as ACE Client.
This describes how to generate it.
2) Checksum Calculation for VISA ICS
The dynamic checksum is function of TTQ options.
This chapter explains how to transcript the VISA ICS features to the TTQ prior to calculate the checksum:
2.1 ) TTQ transcription
...
1.8 Magstripe Mode:
Reflects the MSD Visa Application:
...
1.6 EMV Mode:
Reflects the qVSDC Visa Application:
...
1.5 Emv Contact Chip:
To set if the contact interface is present and used
1.4 OffLine Only:
Static option reflecting this ICS option:
...
1.3 Online Pin:
Reflects this ICS option:
...
1.2 Signature:
Reflects this ICS option:
...
1.1 ODA With online Auth:
Reflects this ICS option:
...
2.8 Online Cryptogram:
Dynamic flag, by default set to 0 (Reset in transaction pre-processing)
2.7 CVM Required:
Dynamic flag, by default set to 0 (Reset in transaction pre-processing)
2.6 Offline Pin:
Not applicable must be set to 0
3.8 Issuer Script:
Reflects this ICS option, not supported by Agnos, must be set to 0.
...
3.7 Mobile CVM:
Mandatory, must always be set to 1.
2.2) Procedure to generate the checksum with ACE Client:
2.2.1)O n any VISA combination add a 0xDF1A tag in other TLV section reflecting the ICS’ TTQ
Such as for example:
DF1A04A7004000
...
2.2.2) Send the ENTRYPOINT updated configuration to the device.
2.2.3) Initiate a PURCHASE transaction
2.2.4) Cancel it on the device
2.2.5) Request the Configuration checksum.
The TTQ displayed after the kernel CLx version, with the checksum must be set accordingly to the VISA ICS TTQ. Even if you change tag 9F66 during the testing the checksum will allways stays at the value reflecting tag 0xDF1A.
