Bitcoin, as Wikipedia tells me, is a peer-to-peer payment system introduced as open-source software in 2009. It’s a ‘virtual currency’ that can be used for transferring money and for buying products or services, although only if your chosen retailer accepts Bitcoin.

Microsoft Tag, which was launched five years ago as an alternative to QR codes, is closing in two years’ time.

This week's podcast begins with a report about a delay - or perhaps even cancellation - for the UK launch of HTC's Facebook phone, the HTC First.

We then move on to Vodafone's results, an Android app scare for Sky, Samsung's successes, contactless payments, potentially life-saving QR codes and an uncomfortable story about a smuggled mobile phone.

Mercedes-Benz says it’ll be adding a QR code to its vehicles, making it easier for the emergency services to help injured occupants.

The barcode, which can be read by most smartphones and tablets, will provide a ‘rescue map’ that shows important information about the specific vehicle.

It feels like many people are hanging on to mobile advertising as the future of mobile marketing.

Yet there's much more to mobile marketing than the banner ad. In this podcast a panel of experts considers the latest trends and innovation that could change the future of marketing.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?

This week's programme begins with some of the biggest news stories that came out of Mobile World Congress.

Iain, James and Mark then move on to the other headlines from the past few days, including Boeing's secret agent smartphone, Apple's plans for mobile in-car entertainment, a new structure for Telefonica and new technology for mobile payments.

London-based Capito Systems won a place on this year's Smart UK Project shortlist, guaranteeing them entry to Mobile World Congress 2014. And when they arrived, they won the international Barca Starta competition as well.

In this podcast we talk to CEO Tony Ballardie about the company’s 'natural language' voice control, which can be integrated into almost any mCommerce application... from gambling to ticket purchases.

Dr Kevin Curran, Reader in Computer Science at the University of Ulster, joined us during Mobile World Congress to offer his well-informed opinion about trends in mobile technology.

We talked about a wide range of topics, including battery life, disposable tablets, wearables, m-health, 4G fragmentation, connected furniture, M2M security, the rise of video and the IEEE.

James Rosewell and Mark Bridge report from Mobile World Congress 2014 in Barcelona.

One of the highlights of Mobile World Congress is the Global Mobile Awards - and this year the event was hosted by James Corden: actor, comedian, TV presenter and one-time promoter of Windows Phone.

Here's how he introduced the ceremony, with jokes about Facebook, BlackBerry, Steve Jobs and the gestures required to control an iPhone.
