I got back from the United Kingdom on October 18. After stepping out of the plane, there were various checkpoints where we were asked to show our health declaration QR code, the Stay Home Safe app installed on our phone, our Hong Kong identity card or passport. We were given different kinds of papers at each of these checkpoints. So I had to hold all these papers, my mobile phone, my hand luggage and my Hong Kong identity card. Instead, all these steps could be consolidated at one checkpoint where the same staff could run through the document checks and app installation, reducing the movement of passengers. All arriving passengers were given, among other things, a badge with lanyards of different colours indicating whether the passenger had arrived from a high-risk location or was exempt from quarantine. Passengers from the UK and other so-called high-risk origin points were given a badge with a red lanyard. However, right after disembarking, we were mingling with people from other flights. People with orange, red and green lanyards were moving around together, taking the same rail link to baggage claim and in the same queue for everything from sample collection to buses for the same quarantine hotel. So what’s the point of triaging people and designating high-risk origins? Once activated, the Stay Home Safe app would send out several notifications a day asking me to scan the QR code on my wristband. The first few days, there would be a “thank you” message when the scan was done. Then, probably on the fourth day, there was no “thank you” message after each scan. I also found that the number of notifications recorded in the app did not match what I actually received. So I called up the hotline. I was told that everything had worked fine and to simply ignore the statistics. Apparently, several months after the app has been in operation, there are still bugs. On the ninth day, a man delivered a sample bag (for another test) and said I could put it outside my room for him to collect the next day. I did not want to do so because the form with my personal details was placed in the outer pocket of the bag. Moreover, why should the personal data be displayed there, when there are already identification codes on the bag and the tube? The next day, a member of “staff” without identification proof came to collect my sample. I hope the government will look into this to minimise the risk of data leakage. K. Lam, Sha Tin
