Biblio::RFID::RFID501 - RFID Standard for Libraries
This module tries to decode tag format as described in document
RFID 501: RFID Standards for Libraries
http://solutions.3m.com/wps/portal/3M/en_US/3MLibrarySystems/Home/Resources/CaseStudiesAndWhitePapers/RFID501/
Goal is to be compatibile with existing 3M Alphanumeric tag format which, as far as I know, isn't specificed anywhere. My documentation about this format is available at
http://saturn.ffzg.hr/rot13/index.cgi?hitchhikers_guide_to_rfid
0 04 is 00 tt i [4 bit] = number of item in set [1 .. i .. s] s [4 bit] = total items in set tt [8 bit] = item type 1 dd dd dd dd dd [16 bytes] = barcode data 2 dd dd dd dd 3 dd dd dd dd 4 dd dd dd dd 5 bb bl ll ll b [12 bit] = branch [unsigned] l [20 bit] = library [unsigned] 6 cc cc cc cc c [32 bit] = custom signed integer

AFI byte on RFID tag is used for security.
In my case, we have RFID door which can only read AFI bytes from tag and issue alarm sound or ignore it depending on value of byte.
secured item (door will beep)
unsecured (door will ignore it)
my $hash = Biblio::RFID::Decode::RFID501->to_hash( $bytes ); my $hash = Biblio::RFID::Decode::RFID501->to_hash( [ 'blk1', 'blk2', ... , 'blk7' ] );
my $blocks = Biblio::RFID::Decode::RFID->from_hash({ content => "1301234567" });
my $blocks = Biblio::RFID::Decode::RFID->blank;
