Secure access control. Access credentials also to smartphones.

Nevertheless, access control technologies also differ, in security, speed, range and serviceability. Older, 125 kHz frequency technologies are now obsolete since they only read a transponder's short, factory-programmed serial number, or UID; making them easy to clone. Conversely, 13,56 kHz frequency (also called 'Smart Card') technologies are over 100 times faster, permitting highly secure transactions and vastly expanded data capacity. The result is 13,56 MHz technologies support the most modern security, data storage and processing capabilities found in access control. (The faster, more expensive UHF, or Ultra High Frequency, is usually only deployed in access control when ranges out to several meters are required.)

Despite these differences, RFID access control has always held advantages over traditional locks and keys: durability, resistance to mechanical wear or breakage. This is because readers and transponders don't need physical contact. Transponder costs are usually much lower than mechanical keys. Controlling access rights is also easier, especially with centrally-administered systems. When a personal transponder is lost, you don't replace locks as when a mechanical key is lost. You simply remove its privileges from your system. Integrating a personal pin code into your system's algorithm adds security that traditional locks can't provide. Lastly, an RFID access control system can let you rapidly create and manage temporary privileges for guests or vendors.
