The program had enabled the imposition of tolls on roads previously built by the Public Works Ministry or the Malaysian Highway Authority (Lembaga Lebuhraya Malaysia, or LLM).

By 18 March 1997, TRACS was enhanced again by Saiful Khairi and his team with the introduction of Touch n Go (pre-paid smart card electronic payment system) at Jalan Pahang Toll Plaza.

Built on a non-stop ETC philosophy, TERAS incorporated SmartTAG infra-red communication, a proprietary technology control by an Austrian company; EFKON Gmnbh that communicated with infra-red transceivers mounted at the ceilings of toll plazas to allow vehicle drivers to drive through SmartTAG dedicated lanes and pay toll without stopping.

As deterrence for Year 2000 problem (Y2K), TERAS was engaged by nine companies under UEM Group to ensure readiness, through creation of internal operations plans continuity in the event of possible technical glitches caused by the Y2K bug.

As counter-measure strategy, TERAS deployed TRACS to other market usages, first as parking automation solution capitalising on Touch n Go platform in 2001.

With the realisation of the need to ensure sustainable growth, TERAS consolidated its business activities into three major segments; Transportation, Property and eBusiness.

The property business segment secured a major US$2.2 million project of Integrated Building Management System with integration of Audio-visual, parking, security access, visitor management and facilities command center of 29-storey commercial office building at KL Sentral Business District, Kuala Lumpur in 2008.

Expanding out from ETC in transportation market, TERAS began development in Traffic Control and Surveillance System (TCSS) and scored major contract worth US$2.7 million with NSE for the setup of NSE Nationwide Traffic Monitoring Center (TMC) at Persada PLUS in 2008. International market penetration was marked by TERAS completed the delivery and installation of ETC works for Bhiwandi–Kalyan–Shil Phata Road in India worth US$1.4 million in 2008.
