POS Hardware Configuration Control for Certification Continuity
A next-generation POS terminal program required a locked hardware and firmware configuration in order to preserve the validity of its safety certification.
Application Overview
The program operates under a certification regime in which the certificate is issued against a specific configuration.
Project Requirements
Safety certification is issued against a specific configuration; a subsequent component change invalidates the correspondence between certificate and product.
Maintaining that correspondence required a stable bill of materials.
Project Configuration
DDR4 3200 8 GB SO‑DIMM with M.2 2242 SATA III 128 GB.
Project configuration as recorded for this program. Current product availability is listed under Products.
Qualification & Implementation
- Components taken through x86 platform compatibility testing.
- Storage configured for reduced power draw and lower heat generation.
- Hardware and firmware configuration was fixed before shipment and maintained under the change-review requirements agreed for this program.
Recorded Outcomes
Hardware and firmware were controlled as one configuration, preserving certification validity. Supply held through material shortages with no recorded production interruption.
Key Engineering Factors
Hardware and firmware controlled together, so the certificate continued to describe the product.
A storage configuration with lower power consumption and reduced heat generation.
Supply continuity maintained during industry-wide component shortages.
