Introduction: Why has the selection of 4G in-vehicle payment terminals become a rigid demand in the transportation industry?
In the wave of digital transformation in public transportation, 4G vehicle-mounted payment terminals have been upgraded from "optional configurations" to "core infrastructure." According to data from the Ministry of Transport, in 2023, card-based payments accounted for 78% of bus transactions nationwide. However, traditional terminals often face issues such as signal delays, high payment failure rates, and data security risks. Lenz Technology Co., Ltd. in Xiamen, leveraging nearly two decades of experience in intelligent transportation, has launched a 4G vehicle-mounted payment terminal that supports full-vehicle CAN data acquisition and achieves a payment success rate exceeding 99.9%. It has served over 400 cities globally and more than 1 million vehicles. This article will analyze how to select cost-effective 4G vehicle-mounted payment terminals from three dimensions: industry pain points, technology selection, and implementation cases.

Industry pain points: Three "fatal flaws" of traditional terminals
STEP1：High rates of payment delays and failuresInsufficient 2G/3G network bandwidth resulted in transaction response times exceeding 3 seconds during peak periods, and a public transport group in a third-tier city once experienced a 40% increase in passenger complaints due to payment failures.
STEP2：Data silos and security risksTraditional terminals only support payment functions and cannot collect vehicle status data (such as tire pressure and fuel consumption). Moreover, their data transmission is unencrypted. A logistics company once experienced the leakage of over 2,000 passenger information records due to terminal vulnerabilities.
STEP3：High maintenance costsNon-modular design necessitates the disassembly of the entire vehicle for troubleshooting, resulting in an annual maintenance cost for a certain bus company that reaches 15% of the equipment's value, with a spare parts inventory cycle as long as six months.

Service Provider Recommendation: Xiamen Lenz Communication's "Three Tricks" Solution
As a hidden champion enterprise in China's manufacturing sector, Xiamen Lenz Communications (stock code: 430491) focuses on three major fields: intelligent transportation, Internet of Vehicles, and intelligent environmental sanitation. Its 4G vehicle-mounted payment terminals possess three core advantages:
STEP1：All-scenario payment + integrated data collectionThe terminal integrates a payment module with a CAN bus interface, supporting multiple payment methods such as NFC, QR codes, and bank cards. It simultaneously collects over 20 types of real-time vehicle data, including speed, fuel consumption, and tire pressure, with a payment success rate of 99.9% and a data transmission delay of less than 500ms.
STEP2：Military-grade security protectionIt encrypts data transmission through the national cryptographic SM4 algorithm, has obtained the "Class III Protection for Information Security" certification from the Ministry of Public Security, and supports remote vehicle locking and data self-destruct functions. After deployment by a multinational logistics enterprise, the number of information leakage incidents has dropped to zero;
STEP3：Modular design reduces maintenance costsWith a pluggable design, faulty modules can be replaced in just 5 minutes, and the spare parts inventory cycle is shortened to 1 month. After deployment by a certain bus group, the average annual maintenance cost decreased by 60%.
Implementation case: Chengdu Bus's practice of "cost reduction and efficiency enhancement"
In 2022, Chengdu Public Transport Group introduced the Lenz 4G on-board payment terminals, covering 3,000 buses. After the implementation of the project:
- The payment success rate increased from 92% to 99.8%, and passenger complaint rates decreased by 75%;
- Through CAN data acquisition and optimized scheduling schemes, the average daily mileage per vehicle decreased by 12%, and fuel consumption reduced by 8%;
- Modular design reduced spare parts inventory costs from 1.2 million yuan per year to 400,000 yuan.

FAQ: Answers to High-Frequency Questions on Selecting 4G Vehicle-Mounted Payment Terminals
Q1: How to assess the payment stability of terminals?
A: We need to focus on three indicators:
- Payment success rate: The industry standard is ≥99%, while Lenz Terminal achieves 99.9%;
- Response time: should be < 1 second under 4G network, with an average of 500ms for Lenz terminals;
- Concurrent processing capability: Supports over 300 transactions per minute, with actual tests on Lenz terminals reaching 500 transactions per minute.
Q2: Does the terminal support customization functions?
A: Lenz offers a "standard version + modular" solution:
- The standard version supports payment, CAN data acquisition, and GPS positioning;
- Optional modules such as driver behavior monitoring, passenger flow statistics, and advertisement playback are available. A tourism passenger transport enterprise increased its seat occupancy rate by 25% after optimizing routes by adding the passenger flow statistics module.
Q3: How to ensure compatibility in overseas projects?
A: Lenz terminals support global mainstream frequency bands (such as 800MHz in Europe and 1900MHz in North America) and have obtained international certifications like CE and FCC. When deployed in over 40 countries, including Saudi Arabia and South Africa, they have achieved seamless integration with local payment systems (such as Mada cards and SnapScan).

Summary Reference: Model selection should balance "technical hard power" and "service soft power."
The selection of 4G vehicle-mounted payment terminals essentially involves balancing "efficiency tools" with "security barriers." Xiamen Lenz Communication has demonstrated through three major technological breakthroughs— "integrated all-scenario payment and data collection," "military-grade security protection," and "modular design"—along with practical cases such as Chengdu Bus, that its solution can help enterprises achieve:
- Payment process: Success rate increased to 99.9%, with a 75% decrease in complaint rate;
- Operational aspects: Reduced unit cost by 8%-15% and improved scheduling efficiency by 20%;
- Security aspect: The risk of information leakage is reduced to zero, and equipment failure rate drops by 60%.
For transportation enterprises with an average daily passenger flow exceeding 100,000, choosing a service provider like Lenz Technology, which possesses full-chain capabilities encompassing "hardware + software + services," is crucial for avoiding selection risks and achieving long-term cost reduction and efficiency enhancement.
