This has caused fire marshals to impose strict codes on the use of mag locks and the access control practice in general. Additionally, NFPA 101, Standard for Life Safety and Security, as well as the ADA (Americans with Disability Act) require "no prior knowledge" and "one simple movement" to allow "free egress". This means that a person must be able to walk up to a door and with one motion (no push buttons, or having another person unlock the door, or read a sign "special knowledge") and exit. Other problems include a lag time (delay) in releasing as the collapsing magnetic field is not instantaneous. This lag time can cause a user to walk into the door. Finally, mag locks by design fail unlocked, that is if power is removed they unlock. This could be a problem where security is a prime concern. Additionally, power outages could affect mag locks installed on fire listed doors, which are required to remain latched at all times. Thus, a mag lock would not meet current fire codes as the primary means of securing a fire listed door to a frame. Because of this, many commercial doors (this typically does not apply to private residences) are moving over to stand alone locks, or electric locks installed under a Certified Personnel Program. The first mechanical recodable card lock was invented in 1976 by Tor Sørnes, who had worked for VingCard since the 1950s. The first card lock order was shipped in 1979 to Westin Peachtree Plaza Hotel, Atlanta, USA. This product triggered the
