Eyewear and clothing brand Oakley has launched a national mobile campaign with four23 to promote its winter 09 apparel range.

The Manchester agency has created a campaign that makes use of QR codes - two dimensional barcodes which can be read using camera phones with code-reading apps.

The custom QR codes have been hidden within ‘digital snowstorm’ displays in windows and in store at Oakley’s flagship O Store outlets, as well as being sited ambiently around key city locations across the UK.

When read on mobile phones the codes take the viewer to an Oakley microsite, designed by four23, where they can potentially win a week-long stay in a boutique Alp hotel and full Oakley kit.

Every visitor accessing the site is also given a unique reference number that they can use to claim a unique Oakley gift in store.

Darryl Hardman, four23 creative director, said: “The QR codes are proving to be highly effective in driving traffic to the Oakley.co.uk and O Stores. The entry levels in the first few days were beyond expectation.”
