code scanners
Today , similar to barcodes , QR codes are scanned in just about every possible situation , including online ticketing , inventory tracking , logistics and shipping . You can even find them on fliers from bands who want you to watch their concerts and music videos online , or to simply visit their website .
Companies also use them to put Google Maps addresses and directions on business cards . Some even contain the code to automatically load a web page or send an email or text to a company ’ s hotline .
The rate of scanning QR codes has increased by more than a third in the last few years . Advertisers love that users can use their smartphones to read a code in a magazine or on a subway ad or poster – it ’ s one of the easiest connections advertisers can have with consumers .
Other types of barcode scanners Today ’ s technology has paved the way for various types of barcode reader innovations , including QR scanners , that include readers of different sizes , uses and costs . They serve a wide range of financial and organisational applications , and are used to price retail items , perform organisational and logistical services , keep track of shipments and manage financial documents . To decide which one you need , you need to take these factors into consideration :
• Capability of the user
• Environment in which the scanning will be done
• Quality of the barcodes being scanned and likeness to other codes
• Type of host computer being used , whether it ’ s a desktop or handheld device , and if fixed or portable
• Necessary volume or throughput of scans required
There are at least four styles of barcode scanners on the market today , that vary between their methods of output . They include :
Wand / pen scanners These barcode readers are small like a pen or wand , and have a photodiode and LED light on their tips . The user waves the tip of the wand / pen over the barcode , where the black and white bars are illuminated by the LED light . The photodiode measures the light ’ s reflection , and the information is transmitted to the host for processing .
2D camera Some barcodes don ' t contain white and black bars , but more like black and white spaces in a 2D , ( two-dimensional ), target . They can ' t be read by standard machines , but usually hold and provide more information than a regular barcode . The pen ’ s light flashes on the barcode , takes a picture of it , and sends it as a digital signal to the host , where the data is decoded .
Laser This type of reader takes more exact light readings , preventing scanner errors or false positives . A laser scanner works when a laser beam is reflected off a mirror and then moved over
