More updates to the code! Short update so as to not bore anyone. Revisions were made so that when the Master tag is scanned a tag can be written to the non-volatile memory. Unfortunately the Master tag has a habit of writing itself to those memory locations a bunch of times and the other tags duplicate themselves as well.

Screen cap of memory registers. Tag #1 is the Master tag

RFID Authenticator Arduino Code

To do:

• Define necessities of code
• Act like commercial version
• Allow new tags to be recognized after scanning master key
• Do not duplicate tags in memory storage
• Pin goes high only when recognized tags are in place
• Different pin goes high when unrecognized tag is scanned (tampered)
• VERY first tag scanned becomes master tag
• Make linkable list of parts

The rest of the posts for this project have been arranged by date.
