Công cụ ký điện tử kê khai BHXH VIETTEL is a Chrome extension developed by giaodichdientu.viettel. It is a free tool that serves as a digital signature support for the vBHXH Web system of Viettel Military Industry and Telecoms Group. The extension aims to ensure the accuracy and safety of detailed records.

The extension acts as a bridge between the website and the digital signature software on the user's device. It facilitates the transfer of record data from the website to the digital signature software. Once the data is successfully signed, the extension pushes it back to the website. The website then processes the data according to the social insurance connection standard and sends the records to the Social Insurance Agency.

Currently, vBHXH has over 100,000 customers using the application. The goal is to gradually transition all these customers to the online vBHXH system for a better user experience. The online vBHXH system eliminates the need for manual submission of records through postal services or direct submission to insurance agencies. The system supports various procedures, including service registration, changes, terminations, as well as insurance premium payments and healthcare claims.
