Seor Jojoba writes "The release of T-Mobile's G1 Smartphone is shifting focus away from push-based barcode scanning, where embedded URLs send you to locations of a vendor's choosing. There is now more interest in pull-scanning, where product information is retrieved from user-specified sources. It may be that QR-Codes and other 2D barcodes will have their thunder stolen by 1970s-era linear barcodes. On the iPhone, scanning a 1D barcode is slow and unreliable. But the G1's improved optics and Android's improved access to image scans has made 1D scanning quick and useful, opening the gateway for killer apps that help people make spending decisions."
