Firms show barcodes can be read from mobile screens via @electronicsnews #mwc2013 @amsanalog #coupons @mobeam
A partnership between Austria-based semiconductor company ams and US start-up Mobeam is designed to make it possible for barcodes to be scanned from a mobile phone screen. The companies claim they have technology which will enable laser scanners in store to scan 1D bar codes displayed on a mobile phone screen for commerce applications that use barcodes such as coupon redemption, loyalty cards, gift cards and tickets. Smartphones use emissive displays from which a common POS barcode reader cannot capture barcode data. Mobeam has developed a light-based communications technology which it claims can overcome the technical barrier preventing mobile phones from interacting with laser scanners. The companies plan to use the ams TMD3990 module which combines a colour light sensing capability with proximity detection and IR LED barcode transmit function.
