A barcode (usually regarded as a word, a barcode) is a small image of lines (bars) and spaces that are pasted on items in retail stores, ID cards, and, person, or location. The code uses a series of vertical bars and spaces to represent numbers and other symbols. Bar code symbols usually consist of five parts: a quiet zone, start character, data character (including optional check character), terminator, and another quiet zone.
Plastic bar code cards are optical machine-readable data representations. It consists of parallel lines, different numbers, and/or letters (depicted by the customer, but usually a number, which can be a continuous or random number provided by the customer in the excel file). Barcode cards are commonly used in membership programs, and help organizations record important data about customers.
There are usually two types of plastic barcode cards, thermal printing barcode cards, and spray printing barcode cards. Thermal printing is durable and clear. Jet printing is cost-effective and is usually the only option for special-shaped cards. The code can be a serial number or a random code. Barcode size: 10-digit 35X15mm, 8-digit 30X12mm, 6-digit 25X12mm.
Following are the brief discussion on the types of plastic card barcode.
Code 93: can encode the same characters as the ordinary code 39 bar code card; uppercase letters AZ; numbers 0-9; and special characters, such as SPACE, minus sign (-), period (.), dollar sign ($), oblique Bar (/), percentage (%) plus sign (+).
UPC-A: This plastic barcode should contain 12 digits. The first eleven digits are provided by the customer. The twelve “check digits” are calculated based on the previous numbers.
Code 39: Able to encode uppercase letters AZ; numbers 0-9; and special characters, such as SPACE, minus sign (-), period (.), dollar sign ($), slash (/), percentage (%) Plus sign (+).
Code 128: This is an alphanumeric symbol that can encode numbers 0-9, uppercase and lowercase letters A-Z, and all standard ASCII symbols. Code128 is variable length-the more characters, the larger the bar code symbol on the finished plastic card.
Codabar: able to encode numbers 0-9 and six special characters, (-) dash, (:) colon, (.) period, ($) dollar sign, (/) slash and (+) plus sign. Each barcode card can also contain start/end characters A, B, C, and D.
Interleaved2of5: This card contains numeric numbers only.
MSI_Plessey: This variant of the Plessey barcode can encode numbers 0-9 and has a variable length.
PostNET: This only digital symbol can encode 0-9 numbers, and can be printed as 5-digit PostNET barcode, 9-digit Zip + 4 PostNET barcode or 9-digit DPBC PostNET barcode.
How it works
Plastic card barcodes are scanned or read by optical scanners or mobile phones, otherwise known as barcode readers, and the rows on the card contain data that can be read by the machine. The barcode scanner can be handheld or built into the counter, such as in a supermarket. Usually, there will be a software package that allows the scanned information/data to be sent to the computer. For example, if the barcode is a number, it can be linked to the customer and display customer information when scanned, or it can be a system that adds points every time it is used. At last, we can conclude the topic that plastic card barcode is a very important and technical card. However, many organizations are preferring to use this type of card due to their own reasons. But typically this card is hardy in one manner. That is for security and information.
