Easy and Flexible Operation

MT41 supports flexible swiping speed from 47 to 470 mm per second with bi-direction therefore either at lower speed or higher speed, forward or backward, barcodes can still be captured easily and successfully.

Reliable and Affordable Solution

Built with superior optics, MT41 can convert all major 1D barcodes in the market into high quality undecoded TTL digital signals and have the economical price point that make it a reliable and affordable solution of barcode slot reader.

Higher Security

The infrared LED version (MT41i) is available for reading invisible barcodes which is printed under an opaque security film. This feature provides higher security for access control applications such as ID check-in/check-out and time & attendance system (TNA).
