2. Use case 1 – requested scan
Medication informer requests a code from Barcode reader
(“please go ahead and read something”)
This triggers the reader to “scan”
Reader sends the encoded content back to the medication informer
(“I have scanned this: ”)
Medication Informer requests an interpretation from the Barcode Processor
(“please decode “ ” to something understandable”)
Barcode processor returns the representation of the object with attributes
(“your code has a GTIN code , exp date xx/xx, serial, etc”)
Next to this, we have further lookup of the product

3. UBP-2: Interpret the content of the barcode
UBP 1: Request a scan
UBP-2: Interpret the content of the barcode
(return a GTIN, NOT the product name)
Product data requester
Medication Administration Informer (HMW)
Barcode Processor
Barcode Consumer
UBP-2
UBP-1
Barcode Reader
These transactions are just for the barcode uses
Examples of other actors that can be grouped to add the functionality:
Inventory Consumer
Product data requester
Inventory manager

4. Use Case 2 – Unrequested / asynchronous scan
Scanner reads the code
“I read ”
Scanner sends the code to the barcode consumer
Here it is
The consumer asks the decoder…
...

5. Medication Administration Informer (HMW) Inventory manager
Inventory Consumer
Medication Administration Informer (HMW)
Inventory manager
Product data requester
Barcode Consumer
Barcode Processor
UBP-2
UBP-3?
Is UBP-3 a new transaction?
What are the approaches?
UBP-1 and UMP-3 are different
UBP-1 is just the request, UBP-3 is just the response, so UBP-3 is common
...?
