Anyone have any data on the reliability of Oyster? My PP has
started playing up lately on the buses; first an occasional beep and red
light, followed by either a successful second swipe or the driver waving
me through. Tonight on the U1 at Brunel the reader wouldn't even produce
an error so I had to fork out cash. Coming back from Uxbridge on a U1,
the first swipe produced no response, the second a red light and a
"Communication Failure" message. I was diving into my pocket for cash
when the driver suggested I try again, and on the third attempt it worked
perfectly.

I rarely use the Tube, so I don't know how its response compares,
Tubs vs. buses. Physically the card looks in perfect shape (I keep it in
my shirt pocket, not in my wallet).
