Photo verification of people or assets can be accomplished in three ways.
You can use the codeREADr app to scan a barcode and then take a photo and capture associated data. With photo postback, the scanned ID is auto-inserted into a cloud-based database hosted by codeREADr and the corresponding photo is stored in a special folder on your Dropbox account and directly linked to the scanned barcode’s ID.
When that ID is scanned again, the app will automatically display the corresponding photo along with any other content you want to display to the app user at the point of service.
Because the ID is auto-inserted into the associated database, you have the option to start with a blank database. We detailed the database building process here.
Using our Webify feature with an existing database of photo URLs, each associated to an ID, you can display the photo to the app user when the corresponding ID is scanned. How? When you upload your database to codeREADr’s servers you will need to include an HTML tag.
Here’s an example of an HTML tag:
Student[Option: Add text here, such as emergency phone numbers or links to content displayed in-app.]
And this is the result:
Note for Dropbox users. If your images don’t require authentication to view but your images are breaking within the app’s response view, you’ll likely need to make a minor change to your image’s URL. Here’s an option one client suggests: At the end of the URL change the ?dl=0 to ?raw=1.
Postback URL or DSU
When using your own servers with PostbackURL or Direct Scan to URL (DSU) service types, you can post back to the app with an HTML tag as you would with the Webify option noted above.
