So this is what's left. This bit here is the chip that does the job
when you're doing chip and pin. The really clever thing is that all of this wire
around the edge, this is essentially an antenna. And so when you're using wireless, the handset gives off a little radio
signal which gets picked up by this wire and it gives just enough to power
the chip to authenticate the transaction and send it back out
through the antenna to be read by the card reader. And the best thing about it - I mean, I know your card looks
a little bit different now, I'll accept that,
but it should still work. So I've ordered a coffee. Here we go. Thank you very much. How much is it? That'll be £3,
please. I'll do that for you

So this is what's left.
00:00:03.016 --> 00:00:06.044
This bit here is the chip
00:00:06.044 --> 00:00:10.006
that does the job
when you're doing chip and pin.
00:00:10.006 --> 00:00:12.044
The really clever thing
00:00:12.044 --> 00:00:15.056
is that all of this wire
around the edge,
00:00:15.056 --> 00:00:18.052
this is essentially an antenna.
00:00:18.052 --> 00:00:21.998
And so when you're using wireless,
00:00:21.998 --> 00:00:24.000
the handset gives off a little radio
signal
00:00:24.000 --> 00:00:26.016
which gets picked up by this wire
00:00:26.016 --> 00:00:29.048
and it gives just enough to power
the chip
00:00:29.048 --> 00:00:32.024
to authenticate the transaction
00:00:32.024 --> 00:00:35.028
and send it back out
through the antenna
00:00:35.028 --> 00:00:38.012
to be read by the card reader.
00:00:38.012 --> 00:00:39.092
And the best thing about it -
00:00:39.092 --> 00:00:42.068
I mean, I know your card looks
a little bit different now,
00:00:42.068 --> 00:00:45.076
I'll accept that,
but it should still work.
00:00:45.076 --> 00:00:47.096
So I've ordered a coffee.
00:00:47.096 --> 00:00:49.999
Here we go.
00:00:49.999 --> 00:00:50.056
Thank you very much.
00:00:50.056 --> 00:00:53.998
How much is it? That'll be £3,
please. I'll do that for you.
