Questions about traceability solutions

I have many opportunities for projects with Beacons in Brazil, mainly in hospital and industrial environments.
For this I have some questions for the community:
Is it possible to develop bracelet stickers to track babies?
What would an internal traceability solution of high value-added hospital instruments look like?
Is there an encapsulation for external use of Estimote Beacons?
How would a traceability solution be in a large outdoor area with Estimote beacons?
