Why can't I just put my (e-)mail address on the device? The person who finds it just needs to give it to the next post office and tell them the receiver will pay for it.
Good question – one of our main aims with LoseProof is to keep your personal information secure (phone number, email address, home address etc).
Although a lot of items get lost relatively close to home, you're right – we're looking at extending the service in the future to offer the option of return postage.
