What is a virtual card in electronic access control systems?

A virtual card in electronic access control systems is primarily considered a digital credential. This type of card functions similarly to a physical keycard but exists in a digital format, allowing users to access secured areas or systems through a smartphone or other electronic devices. Virtual cards can utilize various technologies such as NFC (Near Field Communication) or Bluetooth, enabling convenient and secure access without the need for a physical object.

The use of virtual cards is increasingly popular due to their convenience, ease of management, and integration capabilities with mobile applications, which enhance security protocols. Additionally, virtual cards can often be easily revoked or updated without the logistical challenges associated with replacing physical keycards. Thus, they represent a modern approach to access control, focusing on adaptability and security in a digital landscape.
