    CCA Health Check and Kontrollbox Outage

    4 min read#73

    Swedish cash register law (SKVFS 2014:9 §4 ch. 9§) states that a sale may not be completed if the control unit is unreachable. Therefore Vendion runs an automatic health check on your fiscal box before every payment.

    What is the health check?

    When a cashier logs into the POS – and every five minutes during a shift – Vendion pings your fiscal box to confirm it's responding. You never see the ping if everything is fine; it only becomes visible if something breaks.

    What happens if the box doesn't respond?

    You see a red banner at the top of the POS:

    ⚠️ Fiscal box unreachable — cannot take payment

    At the same time the Pay button is disabled until the issue is resolved. You can still:

    • Place orders and send to the kitchen
    • Park tabs
    • Take orders on mobile or via QR

    The only thing blocked is finalizing payment (i.e. printing a receipt with the control code).

    Why so strict?

    The fiscal box signs every receipt with a cryptographic code. Without the signature the receipt is invalid in the Tax Agency's eyes. If you take payment without a signature, you can face fines and back-taxes. Vendion's block is a safeguard against unintentionally breaking the law.

    How to resolve the outage:

    1. Click the banner – a diagnostic dialog appears with three options:

      • Retry (pings the box now)
      • Cancel (closes the dialog, keeps tabs parked)
      • Contact Vendion (opens support chat)
    2. Check physical basics:

      • Is the box powered on? (Light should be on)
      • Is the network cable plugged in? (LED on the ethernet port)
      • Do you have internet right now? Test on another device.
    3. Reboot the fiscal box:

      • Unplug power for 10 seconds
      • Plug back in
      • Wait 30 seconds for the box to boot
      • Tap Retry in the POS
    4. If the problem persists:

      • Open Admin → Devices
      • Select the workstation
      • Click the Fiscal Box tab
      • Tap Test now
      • If it still fails: call Vendion support (operator contacts AXENA if needed)

    What happens to open orders?

    Orders that were open when the outage started stay parked. No data is lost. When the box is back online:

    1. Banner disappears
    2. Pay button is re-enabled
    3. Open the tabs and continue where you were

    Receipts "stuck" during outage:

    If a payment was started but interrupted when the box went down:

    • The order has status pending
    • The payment did not complete with the card acquirer
    • You'll see it in Order History → Pending
    • Run Retry finalize to re-run the payment

    If the card was already charged but no receipt was printed:

    • Pre-check with the card acquirer (Worldline/Adyen interface)
    • If the payment went through: run Manual Finalize with the control code from support
    • If the payment was cancelled: redo the whole transaction

    How often is the box pinged?

    OccasionFrequency
    LoginImmediate
    Before paymentImmediate
    During shiftEvery 5 minutes
    Overnight (closed)Not at all

    Preventive maintenance:

    • Keep the box in a fixed location – don't move it (it can affect AXENA registration)
    • Ensure vent grilles are dust-free – the box gets warm
    • Draw a network map so you know where it sits when things break
    • Have a backup router or LTE failover if your main router dies

    Emergency: no internet, no box?

    If internet is totally down:

    • You can keep serving guests – take orders, bong, pre-bills
    • Payment must wait until internet is back, or:
    • Take cash without a signed receipt and log it as a fiscal incident (the system handles this automatically when you're back online)
    • Guest can pay via Swish on their own phone; you print a receipt later (within 24h per the law)
