Barcodes sound good, but the RFID reminds me of libraries with thsoe anti thrft magnets in them... and how they erase those magents when you check them out... Not a pretty thought! <L> On Dec 13, 2009, at 7:37 PM, Marie O'Connell wrote: Hi all We need to renumber some of our older accessions and have been considering barcodes with the accession number included. It was suggested to me today that we could be using RFID (radio frequency ID). As I know virtually nothing about them I have an uneasy feeling about applying this technology to magnetic tape boxes and reels. Does any audio visual archive use this technology on its tape boxes and/or reels? Is there any danger to the magnetic tape itself, considering both the box and reel would need the same identifier? Can the actual accession number be put on these so as to be seen visibly? Any thoughts would be much appreciated. Thanks in advance. Cheers Marie
