I would believe by now, Clipper should have resolved the card reader meltdowns on buses and trains (especially Muni), but it seems it hasn't been resolved. If you don't know what I'm talking about, click here for my first story posted on October 13, 2010.
Fortunately, a Clipper representative wrote a comment on my blog explaining why the readers are beeping like hell (more than one RFID card was read at once) and said it should be resolved in November with a software update.
Um... OK, it's now December and where's this software update? On Sunday, I boarded a M-Ocean View train going inbound and had to get off at the next stop because the beeping was was totally annoying. Luckily for me, a K-Ingleside train was right behind.
Want to see the annoyance in action? Here's one of many clips available on YouTube:
Come on Clipper, you can get this annoying problem resolved. Look what the ORCA card organization did, they fixed their readers to say "one card at a time please" which means that the user who used the card reader had more than one RFID card present during the scan.
