One thing you might be already wondering is privacy concerns around sharing locations. eBay Classifieds and our team take heart to these issues. One thing to note is every user of eBay Classifieds has the right to decide whether the details of his/her location are shared. Augmented reality is only used as another interface for this data, there is no additional data generated.
On a lighter note, we created a funny holiday video showing a possible transaction :) Check it out below!
