Since the 1st of April 2014, Belgian Authorities imposed obligatory Social Security Office (ONSS) registration for all on-site personnel working on construction sites. This obligation applies to sites with total contractual construction work value of 500 000 Euros (VAT excluded) or above. Emixis provides an easy way to ensure compliance by registering presence via a mobile app. Upon arrival at the jobsite, workers use intuitive UI on their mobile devices to open MyCheckInAtwork and declare their presence. ONSS registration is done instantly.
