Using the Read‑a‑Card Messaging API

If you are a Windows application developer introducing contactless card technology, you can communicate directly with Read‑a‑Card through our Windows Messaging API. This is the cleanest way to add Read‑a‑Card functionality to your software, by receiving Windows messages from Read‑a‑Card that contain the information you need. You can also send messages back to Read‑a‑Card to change the actions that it takes, depending on the status of your system.
