So many of these "technological solutions" end up being "spherical cow" type things.

RFID might speed up checkout at a library by a small fraction, but you still have the issue that most patrons check out a book or two, you still have to check that the DVD is in the case either way, and the self-checkouts aren't backing up anyway.

(Similarly most libraries have given up on fines, at least around here - the overhead of dealing with them and "scaring" patrons away was much worse than the people actively "stealing" books.)

Not to even get to barcodes (like CVS files) are quite interoperable, and you can relatively easily change one barcode system to another, just my importing the data. RFID readers often need specific RFID tags and it locks you to a vendor (who often promptly goes out of business). Over time things like that get noticed.
