Yes a self cleaner will require before and after. The verification system will be someone looking at the pictures and saying "yeah, that looks like they cleaned up" or "nope, looks like they just kicked a can down the street" and they will then click a button to reward the EMRALS.
Interesting. I assume there would be some employees for this? Those "yeah" and "nope" are coming from the dedicated employee to minimalize the possibility of subjectivity, arent they?
Also, what's your opinion on having the trash picker to have to be able to put the trash on the specific trashcan? As many of us know, there are so many trashcan that's material specific, like organic, paper, can, wet trashes, etc.
To start out with we'll have the employees verifying. Soon we will open it up to the public and have people who can validate it and get paid. It would be great if the person recycles properly at the specific trashcan. The eCan will help them sort it properly by taking a picture and doing some image recognition on it.
