First, constructing your DBB Postback doesn’t require any coding. Easily, just copy and paste based on the instructions below.
The key benefit with DBB Postback is directly updating a validation database stored in our servers in real-time. Thus, you don’t have to export scan records and create a new, updated CSV file to upload to that database. Learn more about creating and managing a barcode database here.
A validation database is a table of barcode values and associated data stored on CodeREADr’s servers for use with your validation Service types. After each scan, you can present the associated data as a ‘response’ to the user if the barcode value exists in that database.
Normally, if the barcode value doesn’t exist in the database, the user will get an Invalid response after scanning that value. However, with DBB Postback, you can enable users to add that value to the database along with associated data (text, photos, etc.). Then, allow them to edit data associated with values already existing in the database.
Also, we save scan records on our server. Then, from the Scans page, you can filter, share, export, or insert it into third-party databases.
DBB Postback only works when the user has Internet connectivity. Also, use it only when you need to add or edit the data associated with the scanned barcode value. If you want to add values to a validation database, use Pattern Validation, which can work online or offline. Learn more about using Validation Pattern Matching here.
