RTA Portal Co has announced it is working to implement vertical and horizontal extension of the system. However, Tim Wallis, the Chairman of RTA Portal Co, said there were "no guarantees" that it would be ready by April 2013. The key challenge being that the technology partner (CRIF Decision Solutions Ltd) cannot implement this change without the correct protocols, which are currently under consideration. Wallis said they were working closely with the MoJ in order to finalise the details of these protocols and that they would "continually assess the system requirements as more detail emerges over the coming weeks and months".
