The recent Archers’ storyline wouldn’t have worked in Beijing. Here, great gantries of traffic cameras see into cars and record who is driving, so a court case which hinged on who was behind the wheel would not play out in months of suspense. The British press periodically runs stories on how much tracking and surveilling we are subject to, while the success of the TV series Hunted showed just how hard it is it to evade detection, and how interested we are in the possibility—but how often do we stop to think about the tensions inherent in the freedoms we enjoy? 

It is difficult to explain just how free life in Britain is to someone in China, and how precious, and conducive to social good, that freedom is, to people at home. Take my recent experiences. Prior to entry at Beijing airport, I was randomly chosen for a health check and required to give a mouth swap. This may have been a benign Covid testing program, but it was impossible to tell from the questions on screen we had to answer—and a mouth swab certainly hands DNA to the authorities. At the university where I was studying, face scans are required for entry on every gate, and visitors must be registered with state ID in advance. Despite not having been in China since prior to Covid restrictions, my face had been pre-programmed into the system and an old photograph flashed up on screen as the barriers opened.  

The first time I used a rental bike to cycle back to campus (the local Boris-bikes come on a monthly scheme, linked to a registered phone number), a message flashed up on my phone telling me that I had gone the wrong way down a one-way bike lane. The banner appeared twice, and the system would not let me lock the bike until I had acknowledged my error. The fact that the GPS system tracks the bikes so closely it knew I had gone against the traffic flow for a couple of hundred metres to avoid cycling across a 4-lane street was a surprise. Since that phone is registered to a Chinese friend, such infractions are also potentially a problem for him. What was less surprising, is the systemic nature of China’s ability to track its people at all times. 

No one uses cash in cities in China; in many outlets and places cash isn’t even accepted. Everyone uses apps like WeChat or Alipay to pay for goods—even at food trucks and casual stalls the vendor has a machine to scan a phone QR code. WeChat is WhatsApp and Facebook and a bank debit card and a travel service and news outlet rolled into one; Alipay, its only effective rival, offers similar. To obtain either account, a phone number is needed, numbers which have to be registered. And to pay for anything, a bank account in the name of the individual must be linked to the account. In other words, the government can choose to know every purchase I make, and its exact time and place. A friend who works in a bank says he uses cash where possible because he doesn’t want his colleagues in the bank to see what he's been buying. 

Transport is also heavily regulated. To enter a train station, a national ID card is needed, which is scanned after bags are x-rayed. To purchase a high-speed train ticket, a national ID card—or passport for foreigners—is required. It might be possible to purchase a ticket anonymously in cash from a ticket window outside the station for an old-fashioned slow train, but one would still need an ID card corresponding to the face being scanned to make it to the platform—and the train station has, of course, cameras at every entrance and exit. 

Cameras are pervasive. Walking through my university campus, where every junction has three or four cameras covering all directions, I occasionally wonder where students find space to have a quick snog. The only place I have not yet noticed cameras is the swimming pool changing rooms, which are communal, and in which I am the only person not to shower naked. There are cameras in the church sanctuary, and cameras on street crossings.
