1. Optimize for quick access: At a networking event, time is of the essence. Make sure your digital business card is optimized for quick access and can be easily retrieved from a smartphone or tablet.

2. Add a personal touch: Personalization is key in converting prospects into paying clients. Use the recipient's name, company, and other personal information to make your digital business card feel more personal and tailored to their needs.

4. Make it easy to share: Your digital business card should be easy to share, either through email, social media, or other digital channels. The more people that see your digital business card, the more opportunities you have to make new connections and generate leads.

5. Follow up after the event: After a networking event, be sure to follow up with any new contacts you made. Use your digital business card to remind them of who you are and what you offer, and to keep the conversation going.

6. Track and analyze: Regularly track and analyze the performance of your digital business card, using metrics such as click-through rate, conversion rate, and bounce rate. This will help you to continually improve your digital business card and maximize its effectiveness.

By following these best practices, you can effectively use your digital business card at networking events to get attention, keep attention, and convert prospects into paying clients.
