To evaluate restaurant POS touchscreen usability, watch the people who will use it complete the same realistic order on each device, in the places and conditions where they would work. Record whether they finish, how many corrections they make, and what they say about the screen. A quick vendor demo at a quiet counter is not enough to answer the buying question.
Set your pass criteria before comparing devices. For example, require every tester to enter the sample order correctly without help, read the final review screen, and reach the payment step without starting a real transaction. If a device fails, find out whether a station change, configuration change, or different device solves the problem before signing.
Choose tasks and positions that match service
Start with the work staff actually do at each station. A counter employee may enter an order while standing under bright lights, with a line forming nearby. A server may hold a handheld at a table, move around chairs, and read the screen from an angle. A manager may need to correct an item while standing beside an employee.
Ask at least one person from each affected role to participate. Include staff who have different levels of familiarity with POS screens. The goal is not to find the fastest employee; it is to see whether the screen supports the team that must use it.
Build one sample order from ordinary menu items and a realistic change. Include an item with a modifier, a quantity change, and a correction before submission. For instance, staff might add two sandwiches, remove one, and add a side without an ingredient. Ask them to review the order and navigate to the payment step. Use a training or demonstration setup that cannot send an order to a kitchen, charge a card, message a guest, or dispatch a courier.
Place a fixed screen where it would actually sit, not wherever the demo is easiest. Check the counter height, viewing angle, reach, and space around the mount. For a handheld, have staff hold it as they would during service and move through the usual ordering area. If a protective case, stand, or tether is part of the planned setup, include it.
Run the check under the lighting expected during service. Daylight through a window and overhead lights can affect the same station differently. If lunch and evening conditions differ, repeat the check in both. Allow normal movement around the station, but keep the exercise simulated rather than asking staff to experiment on live guest orders.
Inspect the screen, touch targets, and case
Before timing or counting anything, ask each tester to read the item names, modifiers, quantities, and total on the review screen. They should not have to guess from an icon or move the device into an impractical position. Note where glare appears and whether a small change in angle removes it without blocking the employee's view of the counter or guest.
Next, watch where fingers land. Small or closely spaced controls can lead to selecting the wrong item, opening the wrong menu, or pressing a neighboring button. Pay particular attention to the controls used to change a quantity, remove an item, and return to the order. Record the correction, even when the employee fixes it quickly.
Try the device with the hands and accessories staff normally use. If employees wear gloves, include them in the simulated check. If hands may be damp during service, follow the device maker's handling instructions rather than creating an unsafe wet-device test. Check whether the case edge makes controls near the screen border harder to reach and whether the device remains comfortable to hold for a full order.
Ask the vendor to show any available display or layout settings on the proposed device. Record what was demonstrated and what remains a question. For example: Can the text size or screen angle be changed? Does the proposed case fit the mount? Will the screen work with the operating system and payment hardware in the quote? Ask for compatibility answers in writing rather than assuming a familiar tablet will work.
Fleksa's hardware information is a starting point for discussing counter terminals, handhelds, and related equipment. Confirm the specific device and connections you intend to use; a catalog listing does not establish compatibility with every existing setup.
Compare a fixed screen and handheld fairly
Give both devices the same sample order, starting point, instructions, and simulated conditions. Have each employee try both, changing the order in which they use them so the second device does not always benefit from practice. Do not coach a tester through a missed step; note the help requested and let the vendor explain the function afterward.
Hypothetical example: Two employees each enter the same order once on a fixed screen and once on a handheld. The agreed pass is correct completion without help, a readable review screen, and no more than one self-corrected touch error per attempt. No real payment or order is sent.
Both employees complete the order on the fixed screen. One makes one touch correction; the other makes none. Both can read the review screen. On the handheld, both complete the order and read the review screen, but one makes two touch corrections while the other makes none. Under the stated limit, the fixed screen passes both attempts and the handheld passes one of two.
That result favors the fixed screen for this sample, not necessarily for every restaurant. The handheld might still be useful if staff need to take orders away from the counter, but it has not met the agreed accuracy criterion for both testers. Ask whether a larger control, different layout, or case change is available, then repeat the same simulated task with the proposed change.
An exception can change the choice. Suppose the fixed screen passes at the counter but glare makes the review screen unreadable from the only position available during lunch. It then fails the readability criterion in that condition. Test a practical mount or location change; if none works, the fixed screen should not be accepted for that station merely because it performed well elsewhere.
Do not treat a short exercise as proof that a device will work through every rush. Once the simulated checks pass, arrange a limited live service pilot if the vendor and restaurant can support one. Set the roles, duration, fallback procedure, and review date first. Live orders and payments belong only in that separate, controlled pilot, not in the practice scenario.
Use an observation sheet to make the decision
The following sheet summarizes the hypothetical comparison above. A correction is an unintended selection or entry that the employee reverses before finishing. Count each correction, not just each order with an error. Record help separately because an assisted completion does not meet the example's pass criterion.
| Observation | Fixed screen | Handheld |
|---|---|---|
| Completed correctly without help | 2 of 2 attempts | 2 of 2 attempts |
| Touch corrections per attempt | 1 and 0 | 2 and 0 |
| Review screen readable | 2 of 2 attempts | 2 of 2 attempts |
| Staff feedback | One tester found the counter position comfortable | One tester reported tapping a neighboring control |
| Result against the agreed criteria | 2 of 2 attempts pass | 1 of 2 attempts passes |
For your own sheet, add the date, station, lighting, device and case, tester role, and order used. Note the exact step where a correction or request for help occurred. Keep comments specific: “could not read the modifier near the window” gives you something to investigate; “screen was bad” does not.
Compare results by station and employee, not only by device average. A screen that works for one person in dim light may fail another person at the same counter at noon. Agree which failures are acceptable to retest and which require a different configuration. If staff need training on a particular step, record that separately from a physical problem such as glare or an unreachable control.
Before selection, ask the vendor to document the proposed device, mount or case, connections, available settings, and any change needed to meet your criteria. Check the operational quote for those items and any setup or replacement charges relevant to your decision. For broader equipment ownership questions, see the hardware buying guide. Contract questions are worth discussing with a qualified adviser.
Next step: Request a demo of the Fleksa restaurant POS system using your sample order and intended station setup. Ask the vendor to document the outcome and any compatibility questions that remain open.
Frequently asked questions
How many employees should try the screen?
Include at least one person from each role that will use the device, and more where schedules or experience differ. A small check can expose problems, but additional attempts across stations and lighting conditions give you a stronger basis for selection.
Should speed determine the winner?
Speed matters, but it should not hide errors or unreadable screens. First check correct completion and corrections against your agreed limits. Then compare time if both devices support the task accurately.
Can we test with our existing tablet?
Ask the vendor to confirm compatibility with the tablet, operating system, printer connection, and processor you plan to use. Do not assume an existing device can be reused just because it has a touchscreen.
