A wand is a handheld optical reader that is used to read barcodes as well as typewritten, printed and OCR fonts. Wands are used to capture product information for retail and warehouse applications.
To read text, the wand is waved over each line of characters in a single pass.
Aiming the wand at a product and pressing the button on Amazon's Wand adds the item to the Amazon shopping cart. See Amazon Wand
