From high security areas such as banks to something as private as your own home, controlling access to specific areas is gaining importance. Card access systems ensure that only those approved can gain access, and can also be restricted to certain time periods.

There are several types of card access systems. The type you might be most familiar with is ID card such as at fitness gyms or wholesale warehouses. There are also the magnetic strip access cards utilized at gyms, secure work environments and even time clocks.
