In life, most of us carry wallets, keys and so on. Our wallet always carries a variety of cards, membership cards, credit cards, ID cards, etc. The more cards you accumulate, the more troublesome it is to find the card you want. Now, we have a different choice. Sweden uses NFC technology to bury the microchip under your skin to make your life more convenient.
The chip is essentially a digital keychain. NFC (Near Field Communication) is a wireless way to send information to readers via passive chips, but only when they are 4 cm (1.6 inches) apart (you may have heard of radio frequency identification, or RFID – NFC is a more For complex forms). A chip in your hand can help people do things like open a car, open an office door, and pay for a credit card. Over time, as technology advances, implanted microchips will be able to do more.
This technology is not new. In fact, since 2015, Swedes and people in other countries have been using microchips. Even before that, people had already gathered at the “implant parties” organized by large companies to connect themselves. These chips are implanted in dogs and cats by veterinary, so that their owners can find them in case they escape or lose.
But now, the ordinary person could implants the chip. Especially in Sweden, these chips are the mainstream chips in Sweden. Since June 2017, people can use their chips to buy train tickets. According to the Associated Press, about 3,000 Swedes have surgically implanted microchips.
But data security issues are a concern for the technology of microchips. Any data connected to the Internet, no matter how safe it looks, is insecure – even NFC can be hacked by using specialized readers and a lot of coding skills. Smartphones have solved this security problem by combining NFC technology with biometrics, just like your fingerprints. But microchips like this don’t have such security, which makes your personal information more vulnerable to hackers, and hopes that the data security issues of the microchip will be well resolved in the future.
