London branches of Tesco-owned restaurant chain Giraffe have begun offering customers daily giveaways through NFC table tents as part of an online advent calendar campaign.

Customers can retrieve a special offer, Christmas tip, free chocolate, an ebook or a toy each day throughout December either by tapping the NFC tag or scanning the QR code included on the cards, provided by NFC marketing specialist Tamoco.

"As early adopters of QR code technology and now with our loyalty app reaching its 15,000th member, working with NFC was a natural step forward for us," says Giraffe co-founder Juliette Joffe. "If this trial at our London sites is a success, we will look to bring NFC into future marketing campaigns in 2014."
