I just had the same problem using an Identive AMID2US00 reader, where our old kiosk readers gave a different number.

These posts gave me the answer to why it was happening.

(using your numbers as example)
Old readers : 4CDDA15F
Identive readers: 5FA1DD4C

After reading this post I noticed the pattern.
1st and 4th bytes were switched
2nd and 3rd bytes were switched

Old readers : 4C DD A1 5F
Identive readers: 5F A1 DD 4C

Is there a bit of software that can interface with e.g. an Identive reader and insert the switched number easily into another application (registration program for cards or when creating lists in excel/database/document) when read?

This would allow us to use the new readers but have them display the old numbers without using multiple steps of conversion of the ID-data.
