This week's edition of The Fonecast starts with an Olympic theme.

We talk about mobile phone coverage at the London 2012 games - and then move on to mobile payments for Olympic visitors. In the middle of the show you'll find a handful of takeovers, Facebook's website and some wireless patents… before we end with a newspaper being fooled by a ghostly iPhone application.

The Microsoft Tag 'colour barcode' is reported to have had its best month since launching in January 2009. More than 50% more tag scans took place in March 2011 than in any other month so far.

Microsoft says the number of scans per month has doubled over the past three months, while the number of users per month has increased 2.5 times in the same period.

Version 6 of the free Opera Mini mobile web browser is now available on the GetJar application store. The news comes less than a month after GetJar removed Opera Mini because it had a link to Opera's own app store.

Opera Mini 6 is available for Android, BlackBerry, J2ME and Symbian platforms.

Samsung and Visa have announced plans to introduce mobile payments to the UK in time for the London 2012 Olympic and Paralympic Games. Both companies are sponsors of the London 2012 event.

There'll be a Samsung Olympic and Paralympic Games mobile phone provided to athletes and also available to the general public. The phone will also require a Visa-enabled SIM card to enable NFC contactless payments.

In this week's edition of The Fonecast we catch up with Bob Sweetlove of HSC. He tells us the secret of winning a Mobile News Award - HSC picked up the 'best airtime distributor' prize earlier this month - and discusses some of the current trends in distribution.

Plus, as usual, we take a look at all the big news stories that affect the UK mobile industry… from developments with the BlackBerry PlayBook to a brand new mobile payment service.
