21.5 Inch Commercial White Android Kiosk: RFQ Preparation Guide for Project Buyers
A request for quotation goes faster and lands on a more accurate price when the buyer hands the factory the same information the engineering team would need to build the unit. For buyers specifying a 21.5 Inch Commercial White Android Kiosk, that means settling the enclosure finish, the touch requirement, the computing configuration, the mounting method and the deployment environment before the first email is sent. This guide walks through each item to decide, what to write down, and which questions to put in front of ZCDISPLAY so the quotation you receive can be compared line by line against competing offers.
Start With the Deployment, Not the Model Number
Project buyers usually open an RFQ with a size and a colour. Those two facts narrow the hardware but they do not determine whether the kiosk survives its first year on site. Write one short paragraph describing where the unit will stand, who will touch it and what it has to do between opening and closing time. A check-in screen in a clinic lobby, an order terminal beside a counter and a product-information panel inside a store each place different demands on the touch layer, the computing board and the service access of the cabinet.
That paragraph becomes the header of your RFQ. It lets the factory propose a configuration that fits instead of quoting the catalogue default, and it gives every supplier you approach the same baseline, which is what makes three quotations comparable at all.
Decide the Touch Layer Before You Ask for a Price
The white-finish 21.5 Inch model is documented with an IPS touchscreen in the product material, but touch technology is a separate decision and it changes both cost and cleaning routine. If your deployment involves food service, medical check-in or an entrance area where people pass through frequently, write down how people will use the screen — bare fingers, gloves, wet fingers — and ask which option the factory recommends for that condition.
Also record whether touch is required at all. A signage-only placement running promotional content does not need a touch layer, and removing it lowers the unit price while simplifying the software stack.
Specify the Computing Configuration in Writing
Android kiosks in this size class are sold with different boards and memory combinations, and the differences are invisible from the outside. The 21.5 Inch white model is documented with Android 7.1, a Rockchip RK3128 quad-core processor and 1GB RAM; other models in the same indoor kiosk family are documented with different Android versions and memory sizes. Do not assume one configuration carries across the range. Ask for the exact CPU, RAM, internal storage and Android version of the unit being quoted, and confirm whether those values can be changed.
Match the specification to the software you intend to run:
| Workload on the kiosk | What to state in the RFQ |
|---|---|
| Looping promotional video and images | Content resolution and duration, whether content is stored locally or streamed, ｕｐｄａｔｅ method over the network. |
| Self-service ordering or check-in app | Name of the application, its minimum Android version, whether it runs alongside other apps, peripherals it must talk to. |
| Point-of-sale terminal | Payment or card reader model, printer interface, whether the kiosk hosts the software or only displays it. |
| Integration with existing IT | Network policy, wired or wireless connection, remote management tool your team already uses. |
List the Peripherals You Actually Need
A kiosk quotation becomes incomplete the moment a scanner, printer or camera appears on site three weeks later. Decide up front which devices must be built into the cabinet and which will sit outside it, then ask the factory to confirm physical fit, driver support and cable routing for each one. Common additions for this format include receipt printers, barcode scanners, card readers, cameras for identity capture and speakers.
- Name the peripheral by model where you already have one; a generic phrase such as "thermal printer" leaves mounting depth and interface open.
- State where the consumable is refilled — front door, side panel or top access — because that determines which cabinet door has to open.
- Ask whether the peripheral is powered from the kiosk or needs its own supply, and who provides the cable.
Fix the Mounting Method and Describe the Site
The 21.5 Inch white model is documented with a stable desktop layout, which suits a counter top or a floor stand in an interior space. If your project needs the unit fixed to a wall or recessed into joinery, raise that in the RFQ and ask what mounting provision the cabinet offers, because the bracket arrangement changes both the drawing and the price. Fanless cooling keeps operation silent, which matters in lobbies and consulting rooms where a fan noise is noticeable.
Then describe the site in numbers the factory can act on: floor space or wall area available, whether the unit stands free, recesses into a counter or bolts to a wall, ambient light from windows, and whether the location is air conditioned. A lobby with direct sunlight and an interior corridor behind a wall need different panel specifications even at the same screen size.
Write the Customisation Questions Early
A white cabinet is often chosen because it matches store furniture or clinic interior standards. Colour matching, a printed fascia panel, a company logo or a different cabinet depth are all customisation requests rather than stock options, and they change tooling time as well as price. ZCDISPLAY presents factory-direct OEM and ODM manufacturing covering engineering through production and quality control, so it is worth putting your customisation list in the first RFQ instead of a later revision round.
For each custom item, state what you need and ask three things back: whether the change is possible on this cabinet, what it adds to the unit price, and how many units must be ordered for the change to apply. Those answers determine whether you are buying a modified standard product or starting a project.
Build the Line Items of the Quotation
Ask every supplier to quote the same structure so numbers line up in one comparison sheet:
| Line item | Detail to request |
|---|---|
| Unit price by quantity band | Price at your target quantity and at one or two higher bands, so the cost curve is visible. |
| Configuration | Screen size, resolution, touch type, CPU, RAM, storage, Android version, connectivity. |
| Peripherals | Each device priced separately, with interface and mounting noted. |
| Customisation | Colour, fascia, logo, cabinet changes — each with its own cost and minimum order quantity. |
| Lead time | Time for a sample unit and time for the production batch, stated separately. |
| Shipping terms | Incoterms, packing dimensions and weight per carton, who arranges the freight leg. |
| Warranty and support | Coverage period, what is excluded, spare-part supply, and the route for a failed unit — see the warranty and support terms. |
Order One Sample Before the Batch
A sample unit answers questions no specification sheet settles: how the touch layer behaves under your application, whether the cabinet colour matches the store furniture in daylight, whether the printer door is workable for the staff who refill it, and whether the software installs cleanly on the board supplied. Treat the sample as a test fixture with a written checklist, and record the results before you approve production quantities.
Confirm at the same time how content gets updated after go-live. If your team maintains its own signage software, verify that it runs on the Android version quoted; if you need a player instead, ask about the Android mini PC options in the product range and compare them with the kiosk's built-in board rather than assuming either one is sufficient.
Questions That Reveal the Supplier Behind the Quote
- Which parts of this unit are made in-house and which are sourced, and who supplies the panel?
- What inspection is performed on each unit before shipping, and is a report provided with the batch? Refer to the quality control process described on the site.
- Which certifications cover this configuration, and are they already held or pending for the customised version?
- Who answers a fault after installation, in which time zone, and what is the expected response?
Distributors and integrators planning repeat orders should also raise the longer-term terms in the same conversation — spare-part availability, configuration continuity across reorders and pricing for later rollouts. The distributor programme page is the starting point for buyers sourcing this format for resale rather than for a single site.
