Fiserv Cardnet North

Cardnet is the North (CES) front-end settling to the North (PTS) back-end — terminal capture. Board it like any Fiserv terminal (see the Fiserv Overview for the shared shape, SRS, and UMF coverage) using the Cardnet North processor config. Note the distinct MID/TID formats.

Boarding spec

Group ID	`30001`	Cardnet / North front-end — a different front-end from Nashville (`10001`).
Merchant ID (MID)	12 digits (`MerchID`)	Cardnet front-end MID, usually the same as the 12-digit Settlement MID. Top-level `mid`.
Terminal ID (TID)	6 alphanumeric (`TermID`)	The "Bank TID". Top-level `tid`.
Settlement MID	12 digits	North Settlement MID. VAR-sheet `settlement_mid` — optional; defaults to a copy of `mid` (which usually equals it).

Capture & settlement

Terminal capture (North PTS). Same as Nashville North — the gateway holds the batch and submits at cutoff. Boarding must match the host's configured capture mode.

Gotchas

Different front-end, different Group ID (30001). Cardnet is not the Nashville front-end — it has its own Group ID and its own MID/TID formats.
12-digit MID, 6-char alphanumeric TID. These formats differ from the 7-digit Nashville/Omaha values — copy them exactly from the VAR packet.
⚠️ MID/TID reversal risk. If the MID is boarded as the TID (or vice-versa) and that reversed combo is live for another merchant, funds route to the wrong account. Confirm deposits before going live.
settlement_mid usually equals the MID for Cardnet; omit it and Koard copies mid.
