Dr Helmi Zakariah, who created SELangkah, cited a study by Oxford University that says “an e-tracing ecosystem is considered effective when 60% of the population uses it”. And since 95% of the Selangor population of 6.2 million uses it, the app passes the threshold of being a scientifically useful e-tracing ecosystem.
Dr Helmi also said that business premises that make use of the SELangkah contact tracing app became surveillance spots for public health workers. As a result, “these business premises become the eye or additional eye for the public health people”. This makes the monitoring and tracing of the disease a little easier. Business premises that use SELangkah as their contact tracing system have their QR code in front. Upon scanning the QR code, visitors will only have to fill in their name and mobile number for the process to be completed. (Source: CodeBlue)
