Answer business questions

  • How many transactions were run yesterday?
  • How many were CHIP and PIN and how many magnetic stripe?
  • Declined for limits, Insufficient funds or EMV failure?
  • How many times was a card used yesterday>
  • How many ATM transactions, how many POS and e-commerce?
  • How many were declined for fraud?
  • How many were recurring scheduled payments?

Intergate legacy systems to REST API

  • Scripting "sensing" of custome integration issues
  • Integrate legacy systems to REST API
  • Detect sudden increase from a specific merchant
  • Detect abnormal use of cards
  • Detect sudden decrease in transactions
 

The ISO8583 Logger will listen to your connection, parse and log ISO8583 messages so you can extract reports.
You can easily then view you transactions in a text file, or import them from a CSV file to Excel, so you can process them and extract reports.
With this kind of answers you can plan better, optimize your configuration, use it to assess granulation for performance testing, and many other things for business presentations and statistics.
