E-parking systems provide information about car parking space availability and allow parking space reservation at a
desired parking lot. A driver can ensure the availability of a vacant car park space when he arrives at the desired parking
lot. Accessing the system can be done using a smart phone, personal digital assistant, short message service or through
Internet. The system must be able to identify the customer that made the reservation or its vehicle and allow them
access to reserved parking space (Chinrungrueng et al. 2007). There are many different implementations of the user
identification process. Some examples are a confirmation code access received on the customer cell phone, printed
receipts, smart cards, magnetic cards and Bluetooth based identification. E-parking has additional benefits like simpler
payment mechanism of aforementioned smart payment system whereby payments by the parking lot users are made
hassle free using e-payment technologies discussed previously (Idris et al. 2010).
