Opening a door with a card is a handy and safe solution to enter a constructing or room. It’s a frequent technique of entry management, particularly in business and residential buildings.
Door playing cards, also called key playing cards, are usually made from plastic and include a magnetic stripe or RFID chip. When the cardboard is swiped or inserted right into a card reader, it sends a sign to a pc system that verifies the cardholder’s identification and grants entry.
