Sometimes referred to as “keyless entry,” an access credential is a virtual key. There are several types of access credentials, including PIN codes, RFID cards and key fobs, or smartphone access. If you’re considering a keyless entry system, you’ll likely use smart locks, software to control those locks, and one or a combination of these access credentials. Your choice of credentials depends primarily on the user experience you desire, but there are other factors (like brand of hardware) that may narrow your choice of credential.
