Q: How do we know
...
if our MiniSmart II readers have a data encryption key injected and how
...
do we verify the injected key
...
is the correct one?
...
A: Follow the steps below to determine key injection status and verify the key:
- To check whether a data key is injected, send the "78 46 30" command using our uDemo to to get the key status and confirm the 2nd second byte from the last is 01 (Refer refer to the
MiniSmart II Command Reference Manual for detail of this command) for command details). - To check which key is injected, send the "78 46 3E 05 00 02 02 00 00 00" command to get the KSN and verify the KSI, which is the first few bytes of the KSN, to confirm it matches your payment processor's key (see screenshot below).
