Opening a door with a card is a handy and safe technique to enter a constructing or room. It’s a frequent methodology of entry management, particularly in business and residential buildings.
Door playing cards, often known as key playing cards, are sometimes fabricated 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.
