Hardware Maintenance Guide
Keep your payment hardware clean, updated, and reliable over time.
Routine Cleaning
Follow each manufacturer's cleaning instructions for touchscreens, print heads, vents, and card readers; use only approved products and methods. Inspect accessible cables for wear without opening tamper-resistant equipment. Regular cleaning prevents buildup that causes malfunctions.
Software Updates
Install firmware and software updates when prompted — these include security patches and feature improvements. Schedule updates during off-hours to avoid disrupting transactions. Keep your POS app current for compatibility.
When to Replace Hardware
Review hardware replacement when a device becomes unreliable, loses manufacturer or security support, or is incompatible with required payment standards. Aging hardware increases downtime risk and may not support newer payment methods. Hardware compatibility depends on processor, gateway, device model, software configuration, and merchant setup.
Weekly Equipment Review
Check cables and chargers for damage, verify paper and battery condition, review approved update notifications, and record recurring errors. Escalate signs of tampering immediately.
Lifecycle and Replacement Review
Check manufacturer support status, security requirements, processor certification, warranty terms, and availability of replacements. There is no universal replacement interval for all payment devices.
