FIELD OF THE INVENTION
The present invention generally relates to wireless communication devices and, more specifically, to a multi-functional wireless communication device.
BACKGROUND OF THE INVENTION
Access control and ticket validation systems have increasingly adopted wireless communication technologies to improve user convenience and system efficiency in recent years. Traditional approaches often require physical interaction, such as swiping a card, inserting a coin, or manually opening a gate. These methods can be time-consuming and prone to wear and tear on the user's access device and the system's infrastructure. Furthermore, users often need multiple devices or cards to access various services, adding to the inconvenience and clutter.
Existing solutions, such as smartphones with NFC capabilities, have addressed issues by consolidating various access control and ticket validation functions into a single device. However, these solutions often rely on complex, power-hungry components, such as large LCD screens, cameras, and mobile communication modules, limiting the device's battery life and overall durability. Additionally, these solutions may only suit some users or situations, as they can be expensive and require a constant internet connection to function correctly.

The multi-functional wireless communication device is designed to be robust and easy to use, making it suitable for a wide range of users and applications.
The inventors first developed systems that include a terminal and a smart mobile device, allowing for wireless ticket validation on buses, wireless parking validation, raising the parking ramp, garage door opening, and similar functions, are as follows:
- Mobile Ticketing and Validation: Many public transportation systems have adopted mobile ticketing, where users can purchase tickets through a dedicated application or mobile website. These digital tickets can be validated using QR codes, barcodes, or NFC technology by bringing the smart mobile device close to a terminal.
- Contactless Payment Systems: Apple Pay, Google Pay, and Samsung Pay have become widely used for contactless payments, including public transportation and parking. These systems use NFC technology to secure transactions between a user's smart mobile device and a terminal.
- Smartphone Garage Door Openers: There are smart garage door openers that can be controlled via a smartphone application through Bluetooth, Wi-Fi, or other wireless protocols. Users can open and close their garage doors remotely and, in some cases, even grant temporary access to other users.
- Access Control Systems: Modern access control systems often integrate smart mobile devices as an authentication method, using Bluetooth, NFC, or other wireless technologies. Users can unlock doors, gates, or ramps by presenting their smart mobile device to a terminal, which verifies the user's identity and grants access.
- Mobile Parking Solutions: Some parking management systems have implemented mobile applications to facilitate parking payments and validation. Users can pay for parking through the application, which communicates with a terminal to confirm payment and grant access.
While significant advancements have been made in integrating smart mobile devices into various validation and access control systems, the inventors found that there is still room for improvement and innovation, particularly in combining multiple functions into a seamless user experience. Newer technologies like UWB and the continued development of existing technologies like Bluetooth and NFC may open further possibilities for more versatile, secure, and user-friendly systems.
Several drawbacks to the above described systems include a terminal and a smart mobile device, allowing for wireless ticket validation on buses, parking validation, ramp lifting, garage door opening, and similar functions. Some of these shortcomings include the following:
- Fragmentation: Many existing systems require separate applications or platforms for different functions, such as public transportation, parking, or access control. This fragmentation can lead to a cumbersome user experience and require users to manage multiple accounts, applications, or credentials.
- Compatibility Issues: Some systems may not be compatible with all types of smartphones or operating systems, limiting their accessibility and usability. In addition, certain terminals may only work with specific wireless technologies, leading to further compatibility challenges.
- Connectivity Reliability: Wireless communication technologies, such as Bluetooth or Wi-Fi, can be susceptible to interference or signal loss, which can impact the performance and reliability of the system. Additionally, reliance on mobile data or Wi-Fi connectivity can lead to potential issues in areas with the poor network coverage.
- Security Concerns: Wireless communication can expose systems to vulnerabilities such as unauthorized access or data breaches. While technologies like NFC offer higher security, no system is entirely immune to potential risks.
- Power Consumption: The use of wireless communication technologies can consume a significant amount of power on smart mobile devices, leading to shorter battery life and potentially inconveniencing users.
- Cost: Implementing and maintaining a wireless validation system can be costly, particularly for small businesses or organizations with limited resources. Upfront investments in hardware, software, and infrastructure, as well as ongoing costs for maintenance and support, can be a barrier to adoption.
- Accessibility: Some users, particularly older adults or those with disabilities, may have difficulty using smart mobile devices or navigating complex interfaces. This can limit the accessibility and inclusiveness of these systems.
- Dependence on Smart Mobile Devices: Relying on smart mobile devices for validation and access control can be problematic if a user's device is lost, stolen, or has a dead battery. In these cases, alternative methods of validation or access may be required, potentially complicating the system.
Despite these challenges, continued advancements in technology and integrating multiple functions into a single, user-friendly system can help address many of these drawbacks and improve the overall performance and utility of wireless validation systems.

System Components
The multi-functional wireless communication device (100) operates within a system that includes a backend system (200), terminals (300), and a mobile application (401) on a smart mobile device (400):
- Backend System (200): The backend system is responsible for processing validation and access control requests in real time (201), verifying the authenticity of the requests, and maintaining user data and system settings. Depending on the specific implementation, the backend system may be hosted on a cloud or a local server.
- Terminal (300): Terminals are external devices connected to the backend system (200) via (201) and communicate with the multi-functional wireless communication device (100) for ticket validation and/or access control. The type of communication depends on the application's needs and requirements (Bluetooth, RF, or UWB). These devices (300) may be installed in the buses at access points, such as public transportation entry gates, parking ramps, or garage doors.
- Mobile Application (401): A mobile application on a smart mobile device (400) connects to the backend system (200) via (202) and enables users to manage the multi-functional wireless communication devices (100) settings and balance.
