When you use a brand new card a 10p authorisation, but not charge, is
made against the account when you first touch in. Nothing else reaches
your account until the end of the day when a single charge for the sum
of all the journeys made is collected and the 10p authorisation
cancelled.

so what happens in the back office if the charge for 28.60 (the cap for
Shenfield to Zone 1) is rejected?

do I get free travel for the day

No, you might get an unauthorised overdraft on your credit card, and quite
likely a penalty charge from the card company.

if you got these it wouldn't be rejected, would it?

The two outcomes are mutually exclusive.

And TfL will probably blacklist the card, so it won't work "tomorrow".

I didn't expect to perpetrate this "scam" using the same card every day. I
had envisaged the need to have multiple cards (though haven't yet worked out
how to acquire sufficient multiple cards)
