Whether its retail, manufacturing, healthcare, warehousing or services industry, VisionID has a barcode scanner that will suit your requirements.
WHAT IS A BARCODE?
A barcode is essentially a message encoded in a set of lines and spaces of different widths.
These messages contain important product information which, when scanned, is interpreted into numbers or letters in order to identify the item. There are two different types of barcode that you may come across in your business: linear and data matrix.
- One-dimensional or 1D Barcode
- Machine readable code consisting of a series of bars and spaces printed in defined ratios.
- Barcode symbology is essentially alphabets in which different widths of bars and spaces are combined to form characters and, ultimately, a message.
- Because there are many ways to arrange these bars and spaces, numerous symbologies are possible.
DATA MATRIX OR 2D BARCODES
- A two-dimensional way of representing information.
- More data representation capability than a linear barcode - consisting of black and white square modules arranged in either a square or rectangular pattern.
- The information to be encoded can be text or raw data.
- Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read.
- Can store up to 2,335 alphanumeric characters.
- Symbol sizes vary from 8×8 to 144×144
TYPES OF BARCODE SCANNERS
Best used in situations where the operator must scan a large number of items in varying shapes or sizes. Can be used to scan codes at a distance, e.g. a pallet stored on the top shelf of a warehouse rack. This means the user does not need to have the item directly in front of them in order to scan it, saving them the time and effort of obtaining better access.
Mounted onto a wall or table, used by passing the barcode under or across its surface. Most commonly seen at the checkout counters in supermarkets and are ideal for small retail operations and institutional organisations requiring accurate and fast-paced data entry. This design has an omni-directional scan, meaning the barcode can be read regardless of orientation, allowing for extremely quick processing.
Some scanners are designed to be connected directly to a defined workstation, such as a PC, laptop or cashiers’ desk through a cable. Corded scanners are well suited to environments where the device will rarely need to be used away from the standard point of use.
Allows the operator to roam up to a 50 feet radius from the scanner’s cradle. Uses Bluetooth or Wireless technology to transmit scanned information to a defined work station. This gives greater mobility for the user when scanning, whilst remaining connected to their work station. Perfect for use in a retail, healthcare or industrial environment.
This type of scanner is typically used where accurate and unattended data entry is required. Different variations of fixed position scanners can be used for scanning items at a long or short working distance, allowing greater flexibility depending on your business’ needs. Barcodes can be read accurately the first time without needing to be perfectly lined up with the scanner.
One of VisionID’s partners Cognex offers fixed mount, handheld and mobile image-based barcode readers that use decoding algorithms and innovative technology to quickly and reliably decipher any code at every time.
