Design Sprint Presentation

We did our design sprint presentation in class. It's about bar-code baggage claim. Other teams also presented in class, in various form, lofi-prototype, real props or slides. We commented to each other and record the feedback.
These are the questions and comments from me：

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.
