Our barcode reader can read all types of codes, which include barcodes, 2D Codes, QR codes, UPC codes, EAN codes, among others. Furthermore, you do not need to install it on your desktop, laptop, or endpoint as it runs from the cloud. Read on to discover why you should use our barcode scanner online, and how to read QR code online.

Benefits of Using Our Barcode Reader API

Bulk Barcode Maker

Our API barcode reader allows you to read your barcodes asynchronously on our servers, or in-house if you use it on your servers. By using our cloud-based asynchronous QR code reader, you can read your codes in bulk. That saves you time allowing you to focus on other aspects of your business.

Easy Integration

Our QR code online scanner includes a built-in OCR, Image Recognition, and it includes a Zapier plugin. With the Zapier Plugin, you can connect it to other web services. Furthermore, our online barcode scanner includes offline SDKs, and it can run from an on-premise API server.

QR Code Scanning Large Files

To use our QR code reader to scan large files without getting a timeout error, you must run the scans in async mode. However, if you want to scan a barcode or barcodes from 100 pages or fewer, then you can run the QR reader API in sync mode.

The Sync mode runs for 25 seconds or less, while the async mode runs for more than 25 seconds, and in the background. It then outputs the QR scan output after it successfully scans all the barcodes.

How to Run to Use Online QR Scanner

Step 1: Request Upload and Access URLs

You need an upload and access URLs that you can use to upload your QR Codes or Barcodes for scanning. To get them to use “/file/upload/get-presigned-url”, this returns a “presignedUrl” that you may use to upload your QR file and a “URL” for accessing the uploaded file.

Step 2: Upload File

You can now upload your file/s using “PUT” to “presignedUrl” that you received in Step 1. Once the upload is complete, you can then access it from the “URL” that you also received in Step 1.

Step 3: Call API Method

Next, you can call the API method with the input set to “URL” param. Moreover, for large files or over 100 pages, set “async” param to “true”, so that the API process can run asynchronously.

The API method will return an output URL, with a matching “jobId” for each output URL. You can use the jobId to identify each background job uniquely, which the API QR barcode scanner is executing.

Step 4: Check Job Status

You can query the online QR scanner for a current job’s execution “status”, using “/job/check” API method with “jobId” param.

Step 5: Download File

Once the “/job/check” returns a “success” as its “status” param, you can go ahead and download the complete QR scans from our online QR scanner.

Conclusion – QR Code Scanner Online Mobile

You can integrate our online scanner to scan documents with your mobile device or upload them for QR scanning on the cloud. For more API code samples, and how to use our code scanner, please check these code samples.
