The Evolis S10175 is an extension board kit designed specifically for the SpringCard Crazy Writer HSP, adding three SAM (Secure Access Module) slots to expand the reader's secure key management capabilities. If your deployment requires multi-application card schemes or additional authentication layers, this is the hardware that makes it possible without replacing the reader itself.

Installation is straightforward for anyone already working with SpringCard hardware — this is an internal hardware addition, so it's worth confirming compatibility with your existing Crazy Writer HSP configuration before ordering. The manufacturer part number is S10175.
