Do you have manypasswordsfor your credit cards(信用卡) or different websites? Do you try to remember them all? As we are advised to have the passwords memorized by heart for safety reasons, not written down, lots of people find it hard to keep them in mind.
However, this problem has been solved by a microchip (芯片) company. The scientists there designed a very small microchip with an electronic circuit(线路). It can identify(识别) you. By putting the microchip under the skin of your hand, you can have access to(有权进人) things with no need for passwords or cards. In this case, it means that you don't have to remember any passwords.
Office workers in Stockholm, Sweden were offered the chance to have the microchip put under their skin if they wish. It allowed them to get in and out of their workplaces and log into(登录) their computers without keys, Besides, they could also use the new technology to pay for the food in the cafe. But some of the workers thought it was a risky idea to have a microchip put under their skin. They considered that the microchip might cause health problems one day.
Anyway, this new technology is fun. With the rapid development of technology, we seem to be on our way to being part human, part machine, don't we?
