For decades, we have been implanting microchips into animals. However, the idea of implanting subcutaneous radio frequency identification circuits into human bodies has aroused the criticism of many relevant workers. Recently, a Dutch security guard named parman stunned the campers when he paid in the store. Parman put his left hand near the payment scanner and finished the payment. Actually, it makes people“Startle your chin”Her operation stems from the implantation of a contactless payment microchip under the skin of her left hand.

As early asone thousand nine hundred and ninety-eightIn, smart microchips were implanted into the human body for the first time. At that time, British Professor Kevin·Warwick implanted the chip into his arm through surgery to carry out various automatic control experiments. However, in order to avoid complications or limited power of the chip itself, in the testnineDays later, the chip was removed. However, this initiative is expected to help disabled people better manage their lives.

in the pasttenOver the years, chip implantation technology began to gradually commercialize. Last year, a company namedWalletmorTechnology companies became the first to sell implantable payment chips. According to the company, such chips have been sold at presentfive hundredMultiple.

according toWalletmorAccording to the company, the implanted payment chip weighs less than a gram, which is a little larger than a grain of rice. It is composed of a microchip and an antenna ring, which are wrapped in natural biopolymers similar to plastic. I usually don't feel the existence of the chip, but when I pay, I feel like someone“Pinch your skin”And you can feel the slight vibration of your hands. The chip can work immediately after being implanted into the human body and will be firmly fixed in place. In addition, it does not need any charging device.

However, with the increasing number of people using this technology, the issue of personal privacy security has also aroused the attention and debate of many people. According to an opponent, implanting a payment chip will lead to the tracking of private information.

Actually, it's not. The technical principle of embedded payment chip is the same as that of other payment methods, that is, wireless communication. The technology used is near-field communication（NFC）, that is, the contactless payment system in smart phones. And most of the chips implanted in the human body are based onRFIDWireless communication technology (commonly used in contactless debit cards or credit cards), because the chip contains an antenna ring, it determines that the payment machine must scan the payment chip within a certain distance.

With the outbreak of the global COVID-19, contactless payment is gradually accepted by people all over the world. It is believed that in the near future, the payment method of contactless chip implantation will also become a popular and common behavior.
