South Korea-based startup LFIN has developed WorkPlus, a blockchain-powered visit verification service designed to help businesses maintain reliable records of employee attendance, client visits, and field assignments. The platform combines multi-factor location authentication with blockchain-based evidence storage to provide verifiable records of employees’ movements outside conventional office environments.
The development comes as companies increasingly adopt flexible work arrangements, creating challenges in verifying employee attendance and confirming visits to client locations, construction sites, and other field destinations. WorkPlus aims to address these concerns by providing businesses with a digital system that records and preserves visit-related information.
KISA Blockchain Project Supports WorkPlus Development
LFIN developed the platform through the Korea Internet & Security Agency’s (KISA) 2026 Blockchain Proof-of-Concept Project for the private sector. The initiative seeks to evaluate how blockchain technology can be applied to practical business operations and everyday activities.
By combining its existing location verification technology with blockchain-based evidence management, LFIN has designed WorkPlus to improve the reliability and transparency of attendance and fieldwork records.
The platform uses multiple location verification methods, including GPS and mobile network base stations, to authenticate employee visits and preserve associated evidence on the blockchain.
Employees can register their visit schedules through the mobile application and activate location verification by selecting the Start Visit option when arriving at a designated location. They can subsequently select End Visit when completing their assignments.
The system captures relevant information, including visit timestamps, location details, and attached photographs. These records are immediately linked to the blockchain, creating tamper-resistant evidence that can be independently referenced later.
The approach is intended to reduce dependence on traditional paper-based documentation and manual verification procedures. It also provides businesses with a more consistent method of confirming whether employees have completed their assigned visits.
WorkPlus Dashboard Simplifies Attendance and Leave Management
Alongside location verification, WorkPlus includes an administrative dashboard that enables managers to monitor employee attendance and field activities.
Administrators can review clock-in and clock-out records, along with the status of employees undertaking external assignments. The dashboard supports searches based on specific periods, departments, employees, and locations, allowing companies to retrieve relevant information without manually reviewing individual records.
The platform also includes an Excel export function that enables administrators to download attendance and visit histories with a single action. This feature is expected to reduce the administrative workload associated with preparing attendance reports, consolidating employee records, and maintaining documentation.
WorkPlus also incorporates leave management capabilities. Employees can submit leave requests and monitor their approval status through the mobile application. Managers can oversee leave administration according to their organization’s internal policies. The platform additionally supports internal survey functions.
By bringing attendance monitoring, field visit verification, record management, and leave administration into one platform, WorkPlus seeks to help businesses streamline workforce management while improving the reliability of operational records.
LFIN Plans to Expand WorkPlus Across Field Operations
LFIN said businesses operating across different work environments increasingly require dependable methods to verify employee movements and external assignments. The company indicated that maintaining reliable records was particularly important for organizations managing client visits, site inspections and other activities that take place away from the office.
The company expects WorkPlus to support more transparent and efficient management of attendance and visit-related operations by combining location authentication with blockchain-based evidence preservation.
LFIN specializes in location-based authentication and artificial intelligence solutions that utilize communications infrastructure, including Bluetooth Low Energy (BLE), Wi-Fi, and mobile network base stations.
The company holds GS Grade 1 certification for its technology and has experience developing various location-based platforms.
Its development strategy for WorkPlus extends beyond conventional employee clock-in and clock-out functions. LFIN plans to expand the service to accommodate a wider range of business activities, including client visits, field assignments, and site inspections.
The broader objective is to establish blockchain-backed verification as a practical tool for businesses that need accurate, traceable, and tamper-resistant records of employee activities across multiple work environments.
