As a new emotional communication carrier, video greeting cards combine the warmth of physical cards with the vividness of digital videos, offering a more immersive communication experience. Compared with traditional paper cards and electronic messages, they possess distinct advantages, including richer emotional expression, customizable content (including shells), strong memory and collection value, wide applicability, and good brand communication effects in commercial scenarios. Video greeting cards are widely used in personal life (e.g., birthday wishes, holiday greetings, wedding blessings) and commercial activities (e.g., customer appreciation, product promotion, employee incentives). To meet diverse needs, they provide various hardware configurations: screen sizes range from 2.4 inches to 10.1 inches, and memory capacities vary from 128MB to 16GB for different video lengths and definitions. In conclusion, video greeting cards have unique value and broad prospects in both personal and commercial fields.
