Check your counter before buying hardware

Inventory what you already own

Write down the exact model, operating system, browser and connection type for the selling device, scanner, printer and card terminal. Photograph labels if the model names are unclear. Record whether you own, rent or lease each item, because a familiar terminal may belong to the old processor. Note the receipt paper width and the cables, adapters, chargers and stands currently keeping the counter usable.

VoVi runs in a browser and can use existing devices, but that does not certify every combination of peripheral, operating system and browser. Treat reuse as something to prove with the actual equipment. A product image or a connector that physically fits is not enough evidence of compatibility.

Run a counter test from start to finish

Scan several real labels, including one with leading zeros and one on a curved package. Confirm that the intended item, variation and price appear, then scan the same item repeatedly to check quantity behavior. Print a short receipt and a longer one. Inspect wrapping, totals, tax labels and any customer details. Disconnect and reconnect the peripheral, then repeat after the device wakes from sleep.

Pay attention to the workspace as well as the connection. A readable screen should not block the customer handoff, and cables should remain secure when the drawer opens. Let the shortest and tallest regular users try the arrangement. Check that receipt paper can be replaced without unplugging the counter and that the payment terminal stays in the position required by its provider. Photograph the working setup so another employee can restore it.

• Confirm the cashier can reach both the POS and terminal without awkward handoffs.
• Check whether a cash drawer opens as required; do not infer this from successful printing.
• Test on the store network with the same permissions and equipment used during trading.

Treat payment equipment as its own decision

Cards are processed on an external terminal. Confirm the supported terminal with the selected processor and document the sale, decline and refund sequence. The US free-software condition still depends on using VoVi’s processor, even though the terminal is external. Keeping another processor means US$99 per month per location for software. Neither choice includes a promise of free hardware, terminal rental or replacement.

Budget for the ordinary failure

Decide what staff do if a charger fails, paper runs out or the store connection drops. Test any proposed backup connection and its payment limitations. Do not assume offline card authorization simply because product search remains available. Keep the equipment list, test result and supplier contact together. Buy only after the essential workflow passes, and include consumables and replacement lead times in the decision rather than comparing device prices alone.
