With the development of science and technology, self-service terminals are undergoing a transformation from "interactive devices with single functions" to "core nodes of intelligent ecosystems". In this process, 5G and edge computing have injected new vitality into terminal equipment in retail, medical, catering and other industries with their unique technical characteristics, building a more efficient, smarter, and safer service system.
1. 5G: Giving Terminals "Extreme Speed Nerves"
As a representative of the new generation of communication technology, 5G has become a key engine for self-service terminals to break through the performance bottleneck with its characteristics of "high speed, low latency, and large connection".
(1) The experience revolution of real-time interaction
In scenarios such as digital ordering, hotel self-check-in, and interactive exhibitions, the immediacy of data processing directly affects the user experience. The 5G network compresses the communication latency between the terminal and the back-end system to milliseconds, and this "zero waiting" experience not only improves the efficiency of order processing, but also increases the utilization rate of self-service terminals in the catering industry by more than 30% by reducing user interruptions.
(2) Stable cornerstones for complex scenes
Traditional Wi-Fi or 4G networks often face signal congestion in high-density areas such as airports and shopping malls, resulting in offline terminals or lag operations. 5G's ultra-reliable low-latency communication (URLLC) technology has built a stable network moat, and even in the extreme environment of tens of thousands of people in the stadium connected to the Internet at the same time, the self-service terminals equipped with 5G can still maintain 99.99% connection reliability.
(3) The game-changing power of AI applications
AI technology is driving the evolution of kiosks from "reactive" to "proactive". The high-speed data transmission capability of 5G makes real-time AI computing possible: in retail scenarios, terminals equipped with facial recognition can instantly analyze the age, gender, and expression of customers, and start the service with a personalized greeting of "Mr. / Ms. XX, welcome, recommend new products of the season for you"; Relying on the low latency feature of 5G, the voice assistant can more accurately understand the user's complex instructions, such as "I want a cup of milk tea with less ice, three points of sugar, and coconut fruit", and the recognition accuracy has increased from 85% to 98%. In addition, the AI recommendation engine can generate customized product combinations in 0.5 seconds based on users' historical consumption data, increasing the cross-sell rate of retail terminals by 25%.
(4) Large-scale deployment of management tools
For chain enterprises, the centralized management of cross-regional terminals used to be an operational problem. The high-bandwidth feature of 5G realizes the efficient linkage of "cloud-terminal": the headquarters can complete the software upgrade of 5,000 terminals nationwide within one hour through the unified management platform, which is 90% more efficient than the traditional manual upgrade; With the help of 5G network, the real-time operation and maintenance system can automatically capture terminal fault logs and push them to the nearest service site, reducing the average time to handle faults from 4 hours to 1.5 hours.
(5) The bearing base of the rich media experience
Immersive interactions such as high-definition video, AR makeup try-on, and VR shopping guide put forward strict requirements for network bandwidth. The gigabit-level transmission rate of 5G easily supports the real-time loading of 4K/8K video streams, for example, in beauty retail terminals, after users click on the AR makeup try-on function, the virtual makeup effect can be rendered in 0.3 seconds and overlaid on the face in real time. The museum's AR navigation terminal seamlessly presents 3D models of artifacts, allowing users to swipe the screen to see details from different angles, increasing the length of time users spend on the device by 50 percent.

2. Edge Computing: Building a Terminal "Intelligent Brain"
Edge computing solves the latency and security bottlenecks of traditional cloud computing by fronting data processing near terminals and forming an "end-edge-cloud" collaborative architecture with 5G.
(1) The efficiency of localization processing has jumped
In the self-service terminal scenario of industrial quality inspection, the part images collected by the camera need to be analyzed for defects in real time. With the help of edge servers, the image recognition algorithm can be processed locally at the terminal, compressing the inspection delay from 2 seconds to 50 milliseconds in the cloud, improving the quality inspection efficiency of the production line by 40 times. At the self-service security checkpoint at the transportation hub, edge computing analyzes baggage X-ray images in real time, reducing the response time of suspicious item alerts from 30 seconds to 2 seconds, greatly improving the timeliness of security prevention and control.
(2) Protective barriers to data security
Medical self-service terminals involve a large amount of patient privacy data, and the traditional cloud transmission mode has the risk of data leakage. Edge computing stores sensitive information such as registration and consultation records on a local encrypted server, and only transmits desensitized statistical data to the cloud. After a tertiary hospital deployed edge computing terminals, the risk of patient data leakage was reduced by 92%, and the compliance requirements of the Personal Information Protection Law were met. In the field of financial self-service terminals, the local encryption processing of edge nodes reduces the probability of transaction data theft from 0.03% to 0.001%, building a strong line of defense for payment.
(3) Emergency safeguards for the network disconnection environment
In remote areas or temporary network failure scenarios, edge computing gives terminals the ability to "offline autonomy". For example, when the 5G signal is interrupted, the self-service ticketing terminal in the scenic spot can rely on the local edge server to continue to process ticket purchase, refund and other services, and the transaction data is temporarily stored locally in the terminal, and automatically synchronized to the cloud after the network is restored. This mechanism improves the service continuity of terminals to 95% in extreme environments, avoiding service disruption caused by network interruptions.
(4) Optimal allocation of computing resources
Edge computing and the cloud form a "hierarchical computing network": simple tasks (such as terminal interface rendering and basic data verification) are handled by edge nodes, and complex operations (such as full user behavior analysis and AI model training) are handed over to the cloud. The self-service checkout terminal of a supermarket chain reduces the load of cloud servers by 60% and improves the response speed of the terminal by 3 times through this model, which reduces the cost of enterprise IT infrastructure by 35% due to the "light edge + heavy cloud" architecture.
3. Converged application: open up a new dimension of industry intelligence
The deep integration of 5G and edge computing is driving the evolution of self-service terminals from "single function carrier" to "ecological hub":
Retail: AR fitting terminals equipped with 5G combined with real-time rendering capabilities from edge computing have reduced the time for customers to try on 10 garments from 30 minutes to 5 minutes, while analyzing try-on data through edge nodes has increased store inventory turnover by 20%.
Medical industry: 5G remote ultrasound diagnosis terminals preprocess ultrasound images through edge computing, compressing the waiting time for diagnosis of experts in tertiary hospitals from 2 hours to 15 minutes, and promoting high-quality medical resources to the grassroots level.
Transportation industry: The highway 5G self-service payment terminal combined with edge computing license plate recognition technology improves the vehicle traffic efficiency from 20 seconds per vehicle to 5 seconds per vehicle for manual toll collection, and the edge node counts traffic data in real time to provide support for intelligent traffic scheduling.
4. Challenges and the future: the dual proposition of technology implementation
On the one hand, the cost of 5G terminal equipment is 30%-50% higher than that of traditional equipment, and there is a financial threshold for large-scale deployment of small and medium-sized enterprises. On the other hand, the localized operation and maintenance of edge computing requires the support of professional technical teams, which puts forward higher requirements for enterprise IT capabilities.
