• In the "Execute transactions and retrieve data in the basic electronic money application" section, I:
  • Added an explanation about what the application can do.
  • Added headings for each type transaction that users can execute in the application.
  • Revised the wording for executing the transactions.
• I also made some minor wording changes and moved a sentence into a note block to better highlight the content.
