Understanding Cosmetic Grades
This certified refurbished terminal is available in Excellent or Good cosmetic condition. Excellent grade units show minimal signs of previous use with only very minor scuffing or light abrasions that are barely noticeable, reflecting careful maintenance by the previous owner. Good grade units remain fully functional with more visible signs of wear such as light scratches or scuffs on the housing from moderate business use. Both grades deliver identical performance and reliability—the difference is purely cosmetic.
Android Operating System Benefits
The Android-based platform offers significant advantages for modern businesses including intuitive operation familiar to most users, flexible customisation options, and seamless integration with a wide range of business applications. Android's open ecosystem enables future software updates and expanded functionality. Whilst requiring occasional software updates like any connected device, the platform's widespread adoption ensures ongoing support and compatibility with evolving payment technologies and merchant services.
