What does one green flash followed by multiple red flashes mean on a vingcard lock?

One green flash followed by multiple red flashes on a VingCard lock typically indicates an access denial. The green flash suggests that the lock has recognized the card, but the subsequent red flashes indicate that the card does not have the necessary permissions or is invalid for that specific lock or area. This could be due to various reasons, such as expired access, incorrect card type, or the card not being programmed for that lock.
