In the future, it can be widely used in scenarios that require long-distance, large-scale, and full-category identification of goods information.
IT Home News on July 22, Alibaba has made great progress in the field of network communication recently, and its self-developed NFC technology has broken the communication limit.
NFC is called “Near Field Communication Technology” in Chinese. As a short-distance high-frequency wireless communication technology, NFC enables non-contact point-to-point data transmission between electronic devices. Compared with other short-range wireless communication technologies, such as Bluetooth, infrared, etc., NFC has the advantages of high security and lower cost. The communication distance is 0-20cm. In fact, most products are within 10cm.
In this breakthrough, Alibaba expanded the traditional near-field communication sensing distance in any direction from 20 cm to 3 meters, realizing “the NFC system with the longest communication distance in the world”.
According to Dr. Liu Hongqiang, head of the Alibaba Cloud network research team, Alibaba’s NFC technology can stably penetrate liquid and metal environments, breaking through the current key bottlenecks in the realization of automated logistics, and can be widely used in the future that require long-distance, large-scale, In scenarios where the product information is identified for all categories, such as logistics, fresh food, and payment scenarios.
In specific applications, NFC has great value in payment, security and tags. NFC payment mainly refers to applications where a mobile phone with NFC function is virtualized into a bank card, all-in-one card, etc. To put it simply, the transportation card, subway card, and bus card for travel is an NFC chip, so a mobile phone equipped with NFC function can be used as a bus card.
In addition, security applications mainly virtualize mobile phones into access control cards, electronic tickets, etc. For example, after a user buys a ticket, a mobile phone with an NFC function can virtualize the ticket information into an electronic ticket, and then just swipe the mobile phone when checking the ticket.
IT House also reported that this achievement was the world’s top conference in the field of network communications Included in SIGCOMM 2020. It is reported that Alibaba has a total of 5 papers selected for the conference, ranking first among all participating Chinese institutions and breaking the Chinese record.
