The 'Food Link' campaign, which was set up in one bus shelter in the area, equipped two posters with NFC tags; one poster displayed a variety of foods while the other showed a picture of a starving child. Bus shelter users were then invited to "connect two worlds — it's in your hands."
With an NFC phone, users could tap on the food of their choice on the poster without the need to download a mobile application. Behind each food item on the poster was its own individual NFC tag, which made the chosen product appear on the user's phone.
They were then required to walk across the bus shelter and tap their phone on the other poster to symbolically give the food to the child. After doing so, users were redirected to WFP's website where they were asked to fill in a form with their payment details in order to donate the cost of their chosen food product.
Grabarz & Partner told NFC World: "We just ran the one campaign as a prototype to check out how the technology works and to see if people want to use NFC. We wanted to see if it's affordable to use it for campaigns in other locations.
"We don't have any actual numbers for the result of the campaign, but we can say that it did have a lot of interest. We have had positive feedback and it was exciting for the people in the town where we had the campaign."
