• Easy to Update Information
  Users can update their contact details, job title, or company information in real-time without needing to redistribute new cards, ensuring contacts always have the latest information.

• Centralized Digital Profile
  The platform allows users to consolidate multiple contact points—social media, website, email, phone—into a single accessible digital profile, streamlining professional networking.

Possible disadvantages

• Dependency on Technology
  Since the card relies on smartphones, QR scanning, or internet access, it may not work well in situations with poor connectivity or when the recipient is unfamiliar with scanning QR codes.
• Limited Brand Recognition
  Compared to established digital business card platforms, Digital QR Card may have less brand recognition, making some users hesitant to trust or adopt the service.
• Learning Curve for Some Users
  Users who are not tech-savvy might find it challenging to set up their profile, generate QR codes, or understand how to share their digital card effectively.
• Potential Privacy Concerns
  Sharing personal and professional information through a digital platform may raise concerns about data security and how the information is stored or used by the service.
• Requires Device for Scanning
  Recipients need a smartphone or device capable of scanning QR codes to access the shared information, which could be a barrier in certain networking scenarios or with less tech-savvy individuals.
