The invention discloses parking charging and 
payment systems and parking charging and 
payment methods thereof. A background 
server prestores vehicle information and generates a related 
payment account, a first identification module identifies the vehicle information at an entrance and sends identification information to the background 
server, the background 
server performs correct matching 
verification and records vehicle 
entry time, a second identification module identifies the vehicle information at an exit and sends identification information to the background server, and the background server performs correct matching 
verification and records vehicle exit time, thus vehicle parking time is calculated, parking fare is calculated according to the rate, and the related fare is removed from the payment account related to the vehicle information. Charging and payment when the vehicle enters and exits from a 
parking lot are completed via the systems automatically, and vehicle entry and exit efficiency is improved; the vehicle information is prestored in the background server, identification and matching accuracy is high, and disordered vehicle management cannot be caused.
