Frequently Asked Questions About How To Start a Food Truck Business
When you scan a barcode what happens?
The scanner captures the barcode either by light reflection or by camera, binarizes the code and then decodes it into meaningful data for the software or POS it is connected to.
Do barcode scanners read the black or white bars?
Depending on the type and capability, barcode scanners read both traditional one-dimensional (1D) bars, and/or two-dimensional (2D) bars such as QR codes.
What method is used to read a barcode?
There are three main methods to barcode scanning: laser, CCD (charge-centered device), and camera-based. The most commonly used scanners are lasers that relay light back into the device to read the black and white spaces in the barcode. The CCD style is similar but uses a series of small LED lights. Finally, the newest technology uses digital camera algorithms to capture and analyze the barcode.
How do mobile barcode scanners work?
Mobile barcode scanners work similarly to wired scanners except that they either connect to a computer/POS via wifi or LTE. Some newer models operate like mini computers that can store inventory and sales data on local memory disks.
Can barcode scanners read QR codes?
QR codes are two dimensional barcodes. Thus, 2D barcode scanners can read QR codes but 1D scanners cannot. Because they are camera based and don’t require an internal light source, 2D scanners can read QR codes both in print and on cell phones.
