Litas POS is a registered cash register with a security module (SM) inside the phone itself. Every receipt is signed and transmitted to the Lithuanian tax authority (i.EKA) — per VA-40.
The receipt is signed by a non-exportable key in the phone StrongBox/TEE. One device = one SM (per VA-40 §31).
Every document is linked to the previous one by its hash. The chain is verifiable and cannot be forged.
The receipt prints a "RECEIPT VERIFICATION · VMI" block (NR, SM, RS, RC) and a QR to kvitas.vmi.lt — the buyer verifies it themselves.
Sales are signed locally and transmitted to i.EKA when connectivity returns. The §26 backlog limit is tracked automatically.
X, daily Z, summary and detailed reports. The full electronic journal (EKJ) — as a download.
Receipt content (§67), fiscal days, returns (§9), cash operations (§71) — to the requirements.
