Please be advised that security improvements are being made to the CSCS Smart Check infrastructure this weekend, which mean the CSCS Smart Check API, app and website will be unavailable between 10am and 2pm on Sunday, 19th April 2026. This timeframe has been selected to ensure disruption is kept to a minimum for users..
During this time, card verification for CSCS cards via CSCS Smart Check will not be possible. We recommend informing site teams and any relevant personnel in advance to minimise disruption.
