How do we know whether our MiniSmart II readers have a data encryption key injected and how to verify the key injected is the correct one?
Step-by-step guide
- To check whether a data key is injected, send the "78 46 30" command using our uDemo to get the key status and confirm the 2nd byte from the last is 01 (Refer to
MiniSmart II Command Reference Manual for detail of this command) - To check which key is injected, send the "78 46 3E 05 00 02 02 00 00 00" command to get 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)
The uDemo screenshot may look different than the later version uDemo, but you should see the same response in the Results window.
