Barcode Slot Reader - Model: BS-412

E-mail Print

It is a durable and reliable barcode slot reader that can be easily integrated into host system via USB or RS232 interface. It is the best partner for access control applications such as ID check-in/check-out and time & attendance system (TNA). Both red LED version and infrared LED version are available for reading ordinary barcodes and invisible barcodes.

Built with a large reading slot, it can accept cards of various sizes. It also 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.

Housed in a rugged and reliable enclosure, it can withstand 1.6 meter drops to concrete and is easy to wipe down and clean as well. Built with superior optics, it can read all major 1D barcodes in the market and have the economical price point that make it a reliable and affordable solution of barcode slot reader.

The infrared LED version 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).

As a plug-and-play USB device, it emulates an USB keyboard and requires no drivers for installation. Simply plug this slot reader into the USB port of host computer and start swiping. It can be also easily configured on the host computer by free user-friendly software tool.
