<p>as an example, say a cash machine dispenses £10 and £20 notes...
you can't guarantee you'll get 20s can you? but what you do know,
is you can get any multiple of 10. so maybe the standard notation
could be that you put currency, the currency code, then the
smallest amount you can get? as the smallest amount is usually
meant to be able to make up any larger amount theoretically that
should be enough. (for example, 5 would declare you can get
anything that is a multiple of 5, 10 would declare anything that
is a multiple of 10). so using that idea you could put
currency:GBP=5, and that would declare it lets you get multiples
of 5, but if you're unsure you can put currency:GBP=yes. i guess
you could also put currency:GBP=5;10;20. there are no other cases
of numerical uses for the currency tag, so it seems like an okay
way to do it<br>

<div>Incomplete data is better than no data. Incorrect data
is worse than no data. The problem with this is that</div>
<div>incomplete (or even complete) data can become incorrect
over time.</div>
<div><br>
</div>
<div>OTOH, we already map other things that are relatively
ephemeral. Opening hours can change. Hygiene certificate</div>
<div>ratings can go up or down. Businesses go bankrupt.
Etc. There's a place near me that was a shop, then a</div>
<div>fast food outlet called "Porky Pies", then an Indian
restaurant, within the last month it became a fast food
outlet</div>
<div>called Deegee's. That's all over the span of about 5
years. It's inconsiderate of them to force me to keep
updating</div>
<div>the map.<br>
</div>
<div><br>
</div>
<div>ATM denominations would be great if there is an effort
to keep it up to date. Maybe suggest that mappers only
tag</div>
<div>it (with whatever tag we decide upon, if we decide to
do it, and if ever we can decide on a tagging scheme) if
they</div>
<div>use that particular ATM at least monthly. Everyone
will ignore the suggestion, of course, and use the tag on
ATMs</div>
<div>they've used only once and will never use again.<br>
</div>
<div><br>
</div>
<div>Maybe I'm just worrying because I can remember the days
when ATMs dispensed £1/£5, then went to £5/£10 and</div>
<div>are now (mostly) £10/£20. Inflation is still present
and bank branches keep closing, so there's more demand for</div>
<div>ATMs. Which means they'll empty faster, which means we
may see £20/£50 soon.</div>
<div><br>
</div>
<div>In the end, though, if enough people want do to it
they'll do it, so all we can do here is try to come up
with a</div>
<div>sensible way of tagging it then document it.<br>
</div>
<div><br>
</div>
<div>We already have currency:XXX=yes/no (a proposal but the
iD editor has supported it for a while). So maybe
something like currency:denomination:GBP=10;20. Then if
there's a locality with two common currencies where an ATM
might dispense</div>
<div>one, or the other, or both, we can use
currency:denomination:GBP=10;20 +
currency:denomination:EUR=5;10 (a</div>
<div>situation we're unlikely to see in the UK, but it's
just an example). There's probably a better way of doing
it, and</div>
<div>people will be along shortly to argue about it. :)</div>
