Uruguay Tests Digital Cards in Nacional’s Copa AUF Uruguay Win
Uruguay has completed its first live trial of digital yellow and red cards, with referee Eduardo Varela using a handheld electronic device during Nacional’s Copa AUF Uruguay last-16 tie against Rentistas on October 15.
The experiment at Gran Parque Central in Montevideo produced a historic first in the 12th minute. Rentistas player Juan Pablo Plada received the first caution shown on a screen after a foul on Maxi Silvera.
How the digital card system works
- Varela used a smartphone-sized device rather than the traditional cardboard yellow and red cards.
- Dedicated controls allow the referee to display either a yellow or red signal on the screen when issuing disciplinary action.
- The same system records key match events immediately, including bookings, dismissals, substitutions, goals and penalties.
- Information is sent directly into Uruguay’s competition-management platform, with the long-term aim of delivering live data to football authorities and media services.
The project has been developed by the Uruguayan Football Association and a technology company. Officials see it as a possible route towards faster, fully digital match administration.
A major part of the design is its ability to operate without conventional WiFi. That could make the equipment useful at grounds with weak internet coverage, including venues outside the top levels of the game.
Visibility remains the key problem
The system is still only an experiment, and the test has exposed a major practical issue: spectators must be able to recognise a booking or sending-off instantly.
In an earlier trial involving Defensor Sporting and Plaza Colonia, bright sunlight reportedly created heavy glare on the device, making its display difficult to see from distance. The problem was less severe under lights at Nacional, but supporters in the stadium and television audiences still found the screen’s colours less clear than a conventional card.
That visibility matters beyond presentation. A physical yellow or red card is immediately understood by players, benches, fans and officials across the pitch. The small digital display has yet to match that clarity.
What happens next
Developers will now work on brighter screen technology and clearer icons capable of cutting through floodlights and direct sunlight. Traditional cards will remain referees’ main disciplinary tool until those concerns are resolved, while the electronic system can continue to support the recording of match data.
