The Kissenger website suggests it's not just for lovers, though: it could also let you connect with family members, planting some sugar on Granny's cheek while you're overseas. What's more, it could also be used "to connect idols and their fans from all around the world" -- even though that sounds like a recipe for stalker creepiness.
Fortunately, Kissenger's still very much in the prototype phase, so there's plenty of time for the team to figure out exactly which niche they'll be targeting. That said, the "experimental kiss transferral device" market's already surprisingly crowded: another device, somehow also named Kissenger, launched back in 2015. That one doesn't seems to have survived the crowdfunding/manufacturing process, though, so there's still an opening for this new Kissenger to swoop in and plant a wet one on consumers across the globe.
