What Goes Into a Custom Payment Terminal
A payment terminal is not a single part — it is an assembly of structural components that must all fit together precisely while housing the PCB, battery, display, NFC antenna, scanner module and charging contacts. We manufacture every structural part in that assembly:
Outer Enclosure
Main body housing display, PCB and interfaces. ABS or PC/ABS, molded or machined.
Housing detail →Battery Cover
Snap-fit or sliding door with latch. Quick-release options for service access.
Battery cover →Scanner Window
Clear polycarbonate window for barcode/QR scanning. Optically flat, low distortion.
Scanner window →Keypad Frame
Button retainer and PIN pad structural frame. Precise tolerances for positive key travel.
Keypad frame →Charging Dock
Desktop cradle aligning the terminal to the charging connector. Custom footprint and angle.
Charging dock →Brackets & Inlays
Internal mounting bosses, PCB standoffs, cable guides and any additional structural inlays.

How a Complete Terminal Build Works
Most clients come to us at one of three starting points. The process is the same regardless of which one applies:
Send what you have
A reference terminal, a competitor unit, photos from all angles, a hand sketch, or partial CAD. We confirm what information we need before you ship anything.
Measure & model all parts
Every structural component is measured and modelled in CAD. For a reference terminal this means disassembly and full dimensional capture of each part — free with your quote.
Confirm drawings
You review a dimensional drawing for each part. We adjust tolerances, wall thickness and interface fits until every dimension matches your intent. Nothing moves to production without your approval.
Manufacture the full set
Prototype runs in CNC machining and vacuum casting. Production runs in injection molding from aluminium tooling. All parts manufactured in the same batch.
Assemble & verify fit
All structural parts are assembled into a complete shell and checked against the original reference. Interface fits, snap features and latch engagement are verified before packing.
Ship — ready for electronics
The complete structural shell is packed and shipped worldwide. Your team integrates the electronics, battery and display into a verified structural fit.
Three Starting Points — All Accepted
You have a reference terminal (competitor or existing product). We disassemble, measure and reproduce every structural part in your chosen material. See payment terminal from sample for the full reverse-engineering workflow.
You have a concept sketch or rough dimensions. We turn your sketch into structural CAD, iterating on each part with you until the design is production-ready. See ordering without CAD for how this works.
You have partial CAD. We complete the missing parts and reconcile tolerances across the full assembly so every component fits as designed.
One supplier for the full structural set. Sourcing each part separately — enclosure from one supplier, battery door from another, dock from a third — means tolerances drift and fit issues appear at integration. We manufacture all parts as a matched set and verify assembly before shipment.
Materials
- ABS — standard outer enclosures and covers; good impact resistance, easy to paint and texture
- PC/ABS blend — higher impact and heat resistance for handheld terminals that take daily drops
- Polycarbonate — clear scanner windows and display bezels; optical clarity and high impact
- Aluminium 6061 — machined chassis and mounting rails where tight tolerance or heat dissipation is needed
Frequently Asked Questions
Typically: outer enclosure, battery cover, scanner window, keypad frame, charging dock, and internal mounting structures. EKINSUN manufactures all of these — individually or as a complete matched set.
Yes. We manufacture the full structural set as a matched batch, verify assembly fit, and ship the complete shell ready for your electronics integration.
Send the reference terminal or clear photos. We disassemble and measure every structural part, rebuild the CAD for each component, confirm drawings with you, then manufacture. CAD reconstruction is free with your quote.
