Wacom Signature Pads are often used in environments where hundreds of signatures are taken every day, e.g. for payment in retail. Thus, robustness is a key requirement for many companies. Several awards from institutions and magazines from various industries as well as customer feedback have proven the quality. Lacking so far was an independent, research-based proof of the robustness of the pads.
Now, a study provided by SGS, the world’s leading inspection, verification, testing and Certification Company, underlines the robustness of the Wacom tablets based on scientific research. Wacom has asked SGS to perform tests with a greater number of signing cycles to check for the possible impact on the surface of a pad. The investigation was on the roughness of the surface.
The results were clear: After 500,000 signings on the pad, there were no scratches visible by naked eye on the pad. Pictures taken by a digital camera showed a surface that could be compared to the initial state of the tablet with one exception only.
For Wacom customers, this means that the STU-530 Signature pad is capable to take half a million signatures with nearly no visible wear. This is unique in the market. If this figure is related to product lifetime, it means that the Wacom tablet surface has a scratch resistance lifetime of approximately 20 years, based on taking an average of 100 signatures per working day. This long, maintenance-free lifetime of Wacom signature pads means a solid investment and a quick Return-on-Invest for companies that use Wacom products.
To run the test, Wacom’s STU-530 Signature Pad had been chosen. SGS set up a mechanical test environment mimicking the actual signature process by writing vectorized electronic signatures on the pad, consisting of lines and circles and being placed in different and varying positions of each sign filed. The load exerted on the pen was about the same as if a real person would have signed. Besides photographic documentation, possible influences on the surface were monitored by using Confocal Laser-Scanning-Microscopy. This method was applied three times: at the beginning, in between and after completion of the tests, confirming the results from optical inspection.
