Direct Scan to URL (DSU)

Direct Scan to URL (DSU) enables the codeREADr mobile apps to post scans directly to your server. Likewise, it enables your server to post the scan response directly back to the app. No scan or response data is posted to codeREADr’s server.

This type of service has the benefits of Postback URL with data security. Also, it enables the use of the codeREADr apps with local area networks. This is useful when you have firewall restrictions or unstable Internet connectivity.

Receiving server responds to the scan

On-Device (offline) record scans or validate scans

The DSU method is based on offline scanning. Thus, the scan response (valid, invalid, response text) would have already been seen by the user before the receiving server receives the post. However, the receiving server must still respond to each scan to acknowledge receipt. Then, the app will not post that scan record.
