Vix Technology argues that rival vendor Modulsystem of Sweden should have been disqualified from the competition to supply thousands of new validators to transport operators in the Swedish capital Stockholm because Modulsystem’s key subcontractor was reportedly involved in a bribery scandal in the Czech Republic, Mobility Payments has learned.
Vix made the contention as part of an appeal (download below) to the proposed contract award for Modulsystem, which transport officials in Stockholm had declared the winner late last month of a procurement to supply up to around 5,000 new validators for Stockholm’s trains, trams, buses and boats, as Mobility Payments reported.
