Figure note: An implantable microchip by Jowan Osterlund of the Swedish company Biohax Sweden, similar to the chip implanted in volunteers at the Australian Mobile Imaging Center. November 3, according to the British "Guardian" reported that the microchip implanted in the human body is only about a grain of rice, usually using a special syringe to implant it between the human thumb and forefinger , and the thickness of this syringe needle is equivalent to a human puncture needle. Kayla Heffernan, an implantable technologist, said that implanting a microchip into the body feels like a shot. Once the needle is removed, the wound healing takes a few days while the microchip remains inside. When the wearer wants to enter a certain place, wave the hand and let the door open. Legend: The microchip is wrapped in a capsule made of inert glass, usually implanted between the thumb and the index finger. Currently, commercial implantable microchips can only accommodate one access code and a small amount of other information, so the days of trying to replace the entire wallet and key with a microchip buried under the skin have not yet arrived. But this day will come, but it will not be too fast. On Wednesday, at the Australian Centre for the Moving Image (ACMI) in Melbourne, 10 volunteers received a microchip, marking the start of the "Pause fest" festival. "Pause fest" is a technology and cultural festival. This year is already the eighth year. Their chips are pre-loaded with a three-day "Pause fest" festival pass that will be reprogrammed in the future to open doors leading to their homes, gyms, and workplaces, or possibly as their public transport pass. When the "Pause fest" festival was held again four months later, the volunteers would join Huffman in a group to discuss whether they thought the chips were useful. Hoffman implanted a microchip between her thumb and forefinger and kept it for nearly 18 months to open her own front door. In November last year, she implanted a microchip on the outer edge of the other hand to open her door at the University of Melbourne office. She is studying for a doctorate in implantable technology applications. After spending a year listening to people talking about the convenience of not having to carry a key, she decided to implant a chip on her own hands. Huffman said: "As long as I think, I can go without carrying any keys. My key is in my hand so I can't forget it. It's very convenient because I used to lock myself before. outside." She said: "Some people use it to unlock a cell phone or a computer. Some people have converted a car for this purpose. One has even modified his motorcycle, so not only can it be used to enter the house, but also can enter the car and start it. Obviously, This requires a lot of microelectronics and physical mechanics, so this will not allow everyone to enter.†Huffman's implanted original chip usually contains a link to her website that can be accessed if someone scans her hands with a Near Field Communication (NFC)-enabled phone. Currently, the site only displays "Hello" information because she is demonstrating that the implanted chip can be reprogrammed. She said that this kind of chip security risk is very low. Huffman pointed out: "The information on this chip must be read in close proximity, so you must touch my hand. Therefore, if someone wants to read the information on my chip, I will know it. For evil purposes, if someone fascinates me, but there is only a link to my site on the chip, there is no useful thing for them to get." Earlier this year, implantable chips became the world's headline news, when Swedish technology company Epicentre made employees voluntarily choose to use implantable chips instead of swiping cards. This was followed by Three Square Market, a technology company based in Wisconsin. Both incidents have raised concerns that the chip may allow employees to be tracked, or allow companies to master their work efficiency, such as being able to record how many times they use the bathroom each day. But Huffman said that this is more of a description of science fiction than real privacy risks. She said that this kind of chip may be used to track the number of visits to the bathroom, but only when employees request to swipe into the bathroom, this feature can also be tracked by ordinary swipes. Hoffman pointed out: "The implanted chips do not have the ability to track, they are not equipped with batteries themselves, there is no GPS sensor ... If someone wants to track you, they will use your phone." The microchip implanted in the human body is no more complicated than the chip implanted on the neck of most domestic pets for more than 20 years. Developers are developing a microchip model that can accommodate multiple numbers, which means that one microchip can store multiple access codes and is developing a microchip with an encryption level that can handle payment transactions. Huffman said: "If you can use it anywhere, whether it is in the workplace, home, gym, just need a chip, people will have more incentive to have this chip. Payment is a killer application As long as you can use it to make payments, more and more people will accept and own such chips." George Hedon, the founder of the "Pause fest" festival, said that he expects most volunteers will try to invade their microchips and that the scope of its application will be expanded by the opening of the event next year. Heden said: "When they arrive, they can also wave in like Darth Vader (the protagonist of the Star Wars)." The “Pause fest†festival, which will take place from February 7 to 9 next year, is expected to involve more than 1,000 participants, 150 speakers and 75 start-up companies. Netflix and NASA will participate in this event. Netflix will discuss the use of artificial intelligence to conceptualize its original work based on population and viewing data. Herden said: "Before their works have been broadcast, they know who will watch. This is terrible, but it is also very effective in raising ratings." (Liu Chun)
