System-sensing access control readers, proximity devices, and transponders are not user-activate readers. In fact, they are the different names for the same thing-system sensing access control readers. This simply means that the system recognizes the presence of an approaching object within a specific area. This type of system does not require the user to swipe the card through the reader. The reader sends out interrogating signals and obtains the access code from the card without the user having to do anything (this would be similar to automated toll-passes). User-activated readers make an individual do something like enter a pin or swipe a card for entry.
