The key card is a small flat card approximately the size of the credit card, which has a digital code built into it, which is inserted that when handing over the key card reader allows the person to insert the digital code. The most common key card types include a magnetic stripe, a mechanical hole card and smart cards. The Magnetic Stripe key card stores data as well as a credit card and provides a magnetic stripe card reader reader information such as the person's name and the area of the building to which the person has access.
The most common use of the key card magnetic lane is in hotels where each room has a unique key card that opens this room only.
