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 limit (72 h / 500 documents) is tracked automatically.
The fiscal memory on the phone is encrypted, and the EJ is also saved daily to a folder you choose and to the server.
The Z report is made automatically at a set time — or right after the phone is switched back on.
Temporary suspension, de-registration, certificate renewal — no tax-office visit, no technician.
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.
