Can you live for a month using only an iPhone to pay for things?

Christina Bonnington sure hopes so.

According to the tech press, one of the "missing features" in the iPhone 5 was the lack of "near-field communications", or NFC, technology. The promise of such tech is that it allows you to turn a phone into a programmable contactless card, and wave it at readers to make payments all day long.

As Matt Drance writes, there was never really any doubt that Apple would not introduce the tech in the iPhone, because although it's a promising technology, it doesn't actually have any use. At least, not today. And so Apple is waiting until it does have some practical applications before moving to roll-out.

In the meantime, one Wired reporter is finding out that it's perfectly possible to make payments with your iPhone today, NFC be damned. Well, not perfectly possible; but doable with a little graft.

Christina Bonnington is living walletless for a month:

You never realize how handy cash is until you don’t have any.

I learned this lesson one day last week when, overcome by hunger, I wandered into the Wired kitchen to grab a bagel for breakfast. I reached into my pocket and suddenly remembered I couldn’t pay for it. See, I’ve decided to spend a month living without a wallet, using my smartphone and various apps to pay for everything. We’re pretty wired here at Wired, but the kitchen still demands cash. Luddites.

Dejected, I went back to my desk and, facing a deadline and unable to venture out into the world, grabbed the first thing that came to hand: a granola bar that’s been sitting in the bottom of my backpack since CES. This culinary disaster was the one setback in what’s been an otherwise flawless week without a wallet, and it taught me a valuable lesson: Be prepared.

We'll see if she can pull it off.

Which CLPs are nominating who in the 2016 Labour leadership contest?

Who is getting the most CLP nominations in the race to be Labour leader?

Jeremy Corbyn, the sitting Labour leader, has been challenged by Owen Smith, the MP for Pontypridd. Now that both are on the ballot, constituency Labour parties (CLPs) can give supporting nominations. Although they have no direct consequence on the race, they provide an early indication of how the candidates are doing in the country at large. While CLP meetings are suspended for the duration of the contest, they can meet to plan campaign sessions, prepare for by-elections, and to issue supporting nominations. 

Scottish local parties are organised around Holyrood constituencies, not Westminster constituencies. Some Westminster parties are amalgamated - where they have nominated as a bloc, we have counted them as their separate constituencies, with the exception of Northern Ireland, where Labour does not stand candidates. To avoid confusion, constitutencies with dual language names are listed in square [] brackets. If the constituency party nominated in last year's leadership race, that preference is indicated in italics.  In addition, we have listed the endorsements of trade unions and other affliates alongside the candidates' names.
