Why does travel itinerary choose the stars? Do you know the reasons behind the stars?
At present, the travel codes of mobile phones are generally provided by mobile phone operators. When their calling cards are online, mobile phone operators can roughly determine the location of their mobile phones through the positioning service provided by GPS satellites.
Travel code has certain significance in the current context, but it still has two major defects. First of all, travel itinerary only determines the location of the inserted mobile phone, or the location where the calling card is inserted into the mobile phone, not the location of the person holding the mobile phone. Then the positioning accuracy in the travel card is low and the delay is large.
Due to the two major defects of travel code, the authority of travel code is greatly reduced and the cost of travel fraud is reduced. So the trip code itself needs to be improved. In terms of accuracy, the travel code should introduce a more accurate positioning system, such as Beidou positioning system. At the same time, the travel card should accurately represent the location of the mobile phone holder, not the location of the calling card in the mobile phone. If this problem is not solved, the existence of tourist cards is of little significance.
Because the travel card cannot represent the location of the mobile phone holder, the current solution is that the mobile phone holder actively scans the location code to obtain the travel information of the person. The location information trajectory obtained by scanning the positioning code can better reflect the location of the mobile phone holder than the travel code, so it has greater significance and is a more scientific and reasonable solution in the current situation.
