3nStar Handheld 2D Scanner with OCR  SC420

The SC420 Handheld 2D Barcode and OCR Scanner is a powerful, versatile tool for retail and semi-industrial environments. Its high-speed imaging engine (60 fps) ensures fast, accurate reading of 1D and 2D barcodes on paper or screens.

With advanced OCR technology, it supports Machine Readable Zone (MRZ) scanning—ideal for IDs, passports, and other official documents. Fully compatible with Windows, Linux, Android, macOS, and iOS, the SC420 fits seamlessly into government, banking, retail, hospitality, healthcare, and industrial workflows.

The OCR technology incorporated in the 3nStar Handheld 2D Scanner, combined with MRZ support, allows for omnidirectional reading of 1D/2D codes, even those of low quality. This scanner also features hands-free operation with an included base, a scan rate of 60 frames per second, and Autosense technology for increased efficiency. With a drop resistance of 1.5mt (5ft), it can withstand accidental drops. Additionally, it is compatible with various operating systems, including Windows, macOS, Linux, Android, and iOS, making it a versatile tool for scanning coupons, mobile tickets, and digital wallets directly from screens.
