Gauteng Roads and Transport MEC Bheki Nkosi said on Wednesday officials would introduce the intelligent number plate system by October this year.
It is part of a crime-fighting initiative which government hopes will assist in preventing car cloning and vehicle theft.
The system will include number plates made of aluminium which will have a passive electronic radio frequency identification tag.
Nkosi said the project would come into effect as soon at the necessary legislation was finalised.
