The payment system log information records the information of the card machine hardware, bus charging software and system problems in the card swipe system, and can also monitor the events occurring in the system. It has important functions such as processing historical data, tracking of diagnostic problems, and understanding the activities of the system.
The bus card system independently developed by Cardlan is based on the Linux system. The Linux system has very flexible and powerful logging functions, which can save almost all the operation records and retrieve the information we need.
The log file of the bus card system can permanently record the event of each user login, logout and system startup and shutdown.

The bus card system log can be a valuable treasure trove of information, or it can be a worthless data quagmire. Log information can record all the behaviors generated by the system and express them according to certain specifications. The bus card system administrator can use the information recorded by the log system to debug the card system, optimize the performance of the system, or adjust the behavior of the system based on this information.

The bus card system log information can collect the desired data, analyze the valuable information, improve the security of the bus card system and products, and help to develop and improve the code and optimize the product.
