OFFLINE MODE

No signal in the freezer?Keep scanning anyway.

Receiving, picking, counting, transfers — every workflow keeps running when the Wi-Fi drops. Klovio writes each scan to a durable local queue with a timestamp, then syncs and merges them in order the moment the network returns. Nothing lost. Nothing double-counted.

Why offline matters

Your warehouse has dead zones. Your inventory shouldn't.

Cold-storage rooms, metal shelving, basement docks, and remote yards eat Wi-Fi. Most scanning apps just freeze, throw an error, or worse — silently swallow the scan. The work stops, or the count quietly goes wrong. Offline Mode treats the network as optional, not required.

The scan that never landed

A picker scans in a dead-zone aisle, the app errors out, and the count never updates. Nobody notices until the shelf and the system disagree by a dozen units.

The work that stops cold

Receiving halts at the cold-storage door because the handheld can't reach the server. A truck waits. A team stands around. Productivity dies in the gaps between access points.

The double-count on reconnect

Naive sync logic replays a queue out of order, or applies a scan twice. The count overshoots, and now you're reconciling a discrepancy that the "fix" created.

Before vs. after

Connection-dependent scanning vs. offline-first scanning.

Same freezer, same dead-zone aisle, same team. The only difference is what happens when the signal drops.

❌ Connection-dependent apps
  • Lose signal, lose the workflow. The scanner errors out and the worker stops until the bars come back.
  • Scans vanish silently. The app accepts the trigger, then drops it when the request times out.
  • Queues replay out of order. A late upload overwrites a newer count and the number drifts.
  • Double-counts on reconnect. The same scan gets applied twice because nothing deduplicates it.
  • Workers retreat to a "good signal" spot. Scanning happens away from the shelf, so accuracy suffers.
  • Cold storage is a no-go zone. Counting freezers means paper, clipboards, and re-keying later.
✅ With Klovio Offline Mode
  • Keep working with zero bars. Receiving, picking, counting, and transfers all run offline.
  • Every scan is committed locally. Written to durable storage with a timestamp before the screen confirms.
  • Merges in chronological order. The queue replays by timestamp, so the count lands correctly.
  • No double-counts, ever. Each queued scan carries an ID and applies exactly once, atomically.
  • Scan right at the shelf. Workers stay where the product is — accuracy goes up, not down.
  • Freezers and yards count like anywhere else. Walk in, scan, walk out. Sync handles the rest.
How it works

Three steps from dead zone to live count.

Scan offline, queue locally, merge in order on reconnect. The worker never sees a spinner, and the count never sees a duplicate.

STEP 01

Scan offline

A worker scans in the freezer or a dead-zone aisle with no connection. The handheld captures SKU, lot, quantity, location, and a precise timestamp — instantly.

0 bars · works
STEP 02

Queue locally

The scan is written to a durable on-device queue before the screen confirms. Restart the device, drop it, swap shifts — the queue survives until it's safely synced.

durable
STEP 03

Merge in order on reconnect

The moment the device sees the network, the queue uploads and replays by timestamp. Atomic operations apply each scan exactly once — no loss, no double-count.

<3 s typical
The durable queue

A scan is committed before it's confirmed.

When a worker pulls the trigger, Klovio writes the scan to durable storage on the device itself — then shows the confirmation. That ordering matters: by the time the screen says "captured," the scan already exists somewhere it can't be lost.

Reboot the handheld, hand it to the next shift, or walk it from a freezer to a loading dock with no signal the whole way. The queue persists, timestamps and all, until every entry is acknowledged by the cloud.

  • Each entry carries SKU, lot, quantity, location, user, and a precise timestamp
  • Survives reboots, app restarts, and battery swaps
  • Confirmed only after the cloud acknowledges the write
  • Visible on-device: workers see exactly what's still queued

Conflict-safe by design

The offline queue and the live engine never fight.

While one device is offline in the freezer, another is online on the dock — both moving the same SKU. When the offline device reconnects, naive systems either overwrite the newer count or apply a scan twice. Klovio does neither.

Queued scans replay by timestamp into the same atomic counters that power real-time inventory. Each entry has a unique ID and applies exactly once. The offline pick and the online pick both land — in chronological order, with no double-count.

  • Replays into the same atomic engine as live scans
  • Per-entry IDs guarantee exactly-once application
  • Timestamp ordering keeps the count chronologically correct

Under the hood

The life of an offline scan.

From a trigger pull with zero bars in the freezer, to a clean, ordered merge into your live count the moment the network returns.
