Re the point about the combined Oyster-ITSO readers, you are of course
totally right - they are hardly an impossibility, indeed to the
contrary they are in essence a requirement for all SWT gatelines in
London.

I don't know anything about the TfL experiment in Harrow (or wherever)
but it sounds interesting.


It was in Brentford. see

Thanks for that. I think I might have that document saved somewhere in
my virtual 'to read' pile after it made a previous appearance here,
but I evidently haven't read it. I will!

A brief glance suggests there were some issues - specifically, from
that executive summary:
"In this pilot, such impacts were not permitted to affect the Oyster
processing times, however this was at the
expense of ITSO card validation times that were very high."

Ah, thanks, I must have been thinking of the original trial of
contactless cards in the mid 90s.
