Design Sprint Video for Bag Tracking Tag

Here is our group presentation for Bag Tracking Tag, we focused on reclaiming baggage faster and more convenient.

Here are the critiques from other groups:
1.how would they cope with multiple bags for the one user? 
2.The potential security problem of our product.
3.Although we can know whether our bags are lost or not, we cannot know how or when it will be back at our hands.
