The RFEF's Technical Committee of Referees is making changes for the Supercopa de Espana, introducing goal-line technology for the first time while improving communication for VAR decisions.
A revamped Supercopa will take place in Saudi Arabia in January, with Real Madrid, Barcelona, Atletico Madrid and Valencia involved.
For the first time in Spanish football, goal-line technology will be implemented in order to aid officials, with previous such calls made with the help of the VAR.
Referees chief Carlos Velasco Carballo explained on Wednesday: "The system consists of 14 cameras on the pitch. A high resolution camera will be on the goal line.
"This system is connected to the referees and, in less than a second, you hear the word 'goal' three times and the watch will vibrates to indicate the goal.
"It's historic in Spanish football."
The use of VAR in the first part of the LaLiga season was also discussed, with Velasco Carballo revealing the system had corrected 19 of 23 officiating errors.
Criticism of VAR has often come from the way calls are communicated to supporters within the stadium, but Velasco Carballo has outlined plans to improve this problem for the Supercopa.
A "Vardict" system on screens aims to ensure fans are kept up to date.
He said: "It will serve to communicate the decisions to the spectators in the stadium, a fundamental aspect in the success of the VAR. They will have the same information as the spectators watching on television."
