Questions buyers ask before ordering
Can’t find yours? An engineer replies within one working day.
Can you put our brand and logo on the display?
Yes. Logo printing, cabinet color, boot animation, launcher and packaging can all carry your brand. This is our most common OEM request.
Which operating systems and chipsets are available?
Android on our own Rockchip RK3288 and RK3399 boards, Windows on Intel Core platforms, and Linux on selected access-control terminals.
Do your products have CE and FCC certification?
Our models hold CE, FCC, CE-RED and RoHS reports, and the factory is ISO 9001 certified. Certification for other markets can be arranged per order.
What is the minimum order quantity?
Standard catalog models can be ordered from 1 unit, so you can test a sample first. For OEM branding and ODM designs the batch MOQ depends on what is customized and is confirmed in the quotation.
How long do samples and mass production take?
Lead time depends on the model, the customization and the order size. We confirm sample and mass-production lead times in writing in the quotation.
What warranty do you offer?
One-year warranty with lifetime maintenance, including remote software support.
Can we get a sample before mass production?
Yes. We build a sample with your configuration and branding for you to test and approve, and mass production starts only after your written approval.
Can you pre-install our software or develop it for us?
Both. We pre-install and test your Android APK or Windows application in kiosk mode, and our software team — building publishing, attendance and kiosk software since 2007 — can develop or adapt the application.
Which modules can a kiosk be fitted with?
Common modules are an 80 mm thermal or A4 printer, QR/barcode scanner, ID or IC card reader, NFC, room-card dispenser, face-recognition camera, payment-terminal bracket and 4G. We test the full combination before shipping.
Do you make displays for outdoor use?
Yes. Our outdoor signage uses 1,500–1,800 nit panels, IP55 galvanized-steel cabinets, temperature-controlled cooling and lightning protection, in fixed and battery-powered portable versions.
How is after-sales support handled for overseas buyers?
Software issues are solved remotely; hardware parts are shipped for replacement under the one-year warranty, with lifetime maintenance after that. Each order gets a named contact for follow-up.
Can we visit the factory or see it on video?
Yes. Visits to our Guangdong factory can be arranged, and if you cannot travel we can run a live video walkthrough of the production and testing lines.
