In Montevideo, during a Copa AUF Uruguay tie between Nacional and Rentistas, referee Eduardo Varela offered a glimpse of a more digital matchday: a yellow card displayed not on cardboard, but on a handheld illuminated screen.
Key takeaways
- Varela first used the electronic yellow card in the 12th minute after Juan Pablo Plada fouled Maxi Silvera.
- The Uruguayan Football Association is testing the system as part of a wider refereeing modernisation project.
- The device is designed to record yellow and red cards, substitutions and penalty decisions.
- Further electronic cautions were shown to Rentistas players before half-time.
- Screen brightness remains a practical issue, particularly for spectators viewing the display from afar.
A trial under the lights of the Copa AUF Uruguay
The moment came early in the Nacional-Rentistas match. When Plada was penalised for his challenge on Silvera, Varela did not reach into his pocket for the familiar yellow rectangle. Instead, he raised a small electronic unit, its full screen turning yellow to signal the caution.
The technology is known within the project as virtual cards. It had already been tested at Defensor Sporting’s ground, where officials identified visibility problems caused by the brightness of the display. Those concerns were again apparent during the Copa AUF Uruguay fixture, with the colour not always easily distinguishable from distance.
Yet the experiment continued through the first half, with Rentistas players receiving further cautions through the same system. The trial placed a new visual element into a competition better known as a domestic cup stage, while carrying implications for refereeing operations across Uruguay.
From the referee’s hand to live match data
Marcelo de León, who leads the AUF’s refereeing department, described the device as a tool intended to handle the full sequence of major match incidents. Alongside cautions and dismissals, it can register substitutions and penalties, linking what occurs on the pitch to the competition’s information systems.
The system does not require a Wi-Fi connection. Its purpose is to reduce the referee’s reliance on handwritten notes and make administrative work quicker, including in youth football.
The AUF is developing the initiative with a private partner so that match events can be delivered live to the COMET platform and the association’s own system. In time, the plan is for that information to be available to the media as well.
There are technical refinements still to make, above all around screen clarity. But Uruguay’s trial points towards a model in which the disciplinary signal, the referee’s record and the live flow of competition data can be produced through a single device.
