INGENIEUR Considering the factors above, there is a need for a total revamp of the system to improve security, process delivery and cost optimization while incorporating new current technology practices in the green card system. GREEN CARD: RFID TECHNOLOGY POTENTIAL & APPLICATION Basically RFID is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data, for the purpose of automatically identifying and tracking tags attached to objects. Some tags are powered by battery and operate over a few metres via magnetic fields and then act as a passive transponder to emit microwaves or UltraHigh-Frequency radio waves. Others use a local power source and may operate over hundreds of metres. Unlike a barcode, the tag does not necessarily need to be within line of sight of the reader, and may be embedded in the tracked object. The history of RFID can be traced back to early 1940s during World War II when it was used to identify allied and enemy aircraft. The technology started to evolve and has been widely used in various applications such as: Tracking persons and animals, ●● Access management, ●● Identifying and tracking goods and ●● assets, Toll collection and contactless payment, ●● Machine readable travel documents, ●● Tracking sports memorabilia to verify ●● authenticity, and Airport baggage tracking logistics. ●● RFID in Construction In the construction industry, the application of RFID has a huge potential to be exploited. RFID tags allow information to be read contactlessly, or written and fixed to tools, people or materials used in the sector. As a result it is possible to track and trace individual items through what has been termed as the ‘Internet of things’. In term of handling site workers and resources, it can improve the quality of project management by replacing manual data collection methods with automated ones which are faster and more reliable for detail analysis. Furthermore RIFD can help make information 6 40 VOL 58 APRIL 2013 2014 VOL 55 JUNE – JUNE about assets or resources more readily available by enabling the collection and consolidation of information for reporting and auditing. Such applications will result in improving accountability by establishing who did what with which, where and when. The applications of RFID specifically in the construction sector are as follows: Access control to sites or areas within ●● sites and monitoring security staff activities on site, Health, safety & environmental ●● compliance, Maintenance control and management, ●● Control of the location of valuable assets, ●● Material identification and tracking, and ●● Plant equipment tracking and control ●● Looking at such potential, CIDB Malaysia carried out a RFID pilot project by incorporating the system into the green card infrastructure called GCSRS. This system is an approach to install RFID chips in the current CIDB’s green card that is currently used by construction industry workers. Such a system allows the full benefits of a smart communication system and provides the platform for online initiatives where CIDB could shift their manual form-filling to a computerised and Internetbased system for daily operation management with their clients. The current green card only displays information of workers printed on the card without any ‘smart’ technology embedded. GCSRS implementation, allows the RFID card to be used in many applications similar to the Malaysian’s Identity Card. The memory within the card can be retrieved and stored electronically when needed by using an appropriate RFID device. Furthermore, RFID card functionality can be fully utilized with the application of a new integrated RFID counter system that could increase the efficiency of the counter service. Instead of using a manual key-in approach when searching card data in the database, the application of a RFID scanner will speed up the search process and cut queuing times at the counter. Similarly CIDB’s enforcement teams can use a RIFD scanner during site checking. The enforcement officer just needs to bring along the RFID mobile reader (validator), which could be used to check and validate the construction personnel card instantly on site instead of using the old method of manually checking the attendance list.
