Swipe card systems work by swiping a plastic card through a device with a reader.
A magnetic strip on the card contains an authorised code. The reader decodes this information to grant access the user.
Swipe card readers are often seen on access to reception areas or office blocks.
Similar systems use a 'swipe tag' or 'key fob' - these systems are known as 'Proximity Readers'.
Proximity readers can be combined with keypads or built into intercoms and are more commonly specified for external gate system applications.
