Are there any free scanning libraries with PDF417 capability available to integrate with iOS apps?
If it supports Android, then that would be even great.
Try RMScannerView:
Simple barcode scanner UIView subclass for iOS apps. Quickly and efficiently scans a large variety of barcodes using the iOS device's built in camera.
It is the only free project I've found that supports also PDF417 barcodes:
Scan Aztec, Code 128, Code 39, Code 39 Mod 43, Code 93, EAN13, EAN8, PDF417, QR, and UPCE codes.
I tried it and it works fine.
The current AVFoundation support PDF417 metadata. Too late to answer but if this is still required, AVFoundation solves the issue. Just add the following code to the scanning session:
let metadataOutput = AVCaptureMetadataOutput()
metadataOutput.setMetadataObjectsDelegate(self, queue: DispatchQueue.main)
metadataOutput.metadataObjectTypes = [.pdf417]
Hope this helps someone.
