Profile: Paxton Access Ltd. manufactures access control systems. Standalone access control type of system may be used to control access on one or many independent doors in a building. Access is gained by using a numeric code, or PIN with a keypad, or by presenting a proximity or Magstripe token, depending on which type of reader is fitted. These systems are programmed at each door. If tokens need to be barred or codes changed, this action must be completed at every door on the system.
