条码（barcode）是将宽度不等的多个黑条和空白，按照一定的编码规则排列，用以表达一组信息的图形标识符。

条码分类：一维码和二维码

一维码：只能表示一定的字母和数字，需与数据库连接，用於商品编码丶积分卡丶购物卡丶消费卡丶会员卡等。常用的条码型号有：CODE39， CODE128，EAN13，EAN8，UPC-A

二维码：多行组成的条形码，无需连接数据库，本身可存储大量数据，二维码的字符集包括所有128个字符，最大数据含量是1850个字符。二维码内容可以是网址，只要有装有二维码扫描软件的手机就可以读出网址，直接登录网站。二维码内容也可以是个人资料信息，通过扫出二维码，就能将个人信息记录在手机上，所以，目前很多的名片设计上都会增加二维码。

Barcode Card Types

• Code 39: Capable of encoding uppercase letters A-Z; digits 0-9; and special characters such as SPACE, minus (-), period (.), dollar sign ($), slash (/), percent (%) and plus (+).This barcode can be of any length, but the more characters encoded, the larger the symbol will be.

• Code 128: This is an alphanumeric symbol capable of encoding digits 0-9, upper and lowercase letters A-Z, and all standard ASCII symbols. Code128 is variable length—the more characters, the larger the barcode symbol will be on the finished plastic card.

• Code 93: Capable of encoding the exact same characters as normal Code 39 barcode cards; uppercase letters A-Z; digits 0-9; and special characters such as SPACE, minus (-), period (.), dollar sign ($), slash (/), percent (%), and plus (+). The only difference is that this barcode symbol is more compact.

• UPC-A: This fixed-length, numeric-only symbol must contain 12 digits.

• EAN_JAN-13: This fixed length, numeric-only symbol is similar to the UPC-A, but encodes 13 characters instead of 12.

• EAN_JAN-8: This fixed-length; numeric-only symbol is a compressed version of the UPC-A. All bar code cards must contain 6 digits and because the UPC-E is used for the number system, all symbols must begin with a zero.

• UCC_EAN128: This symbol is capable of encoding the same characters as a normal Code 128 barcode; digits 0-9; upper and lowercase letters A-Z; and all standard ASCII symbols. However, the UCC/EAN 128 Barcode formats the data in a different way so that the type of information encoded can be identified. This is done with application identifiers. These 2, 3, or 4 digit numbers are enclosed in parenthesis and identify the type of data that follows.

• UPC_E: This fixed-length; numeric-only symbol is a compressed version of the UPC-A. All barcodes must contain 6 digits, and because the UPC-E is used for the number system zero, all symbols must begin with a zero.

• CodaBar: Capable of encoding digits 0-9 as well as six special characters, (-) dash, (:) colon, (.) period, ($) dollar sign, (/) slash and (+) plus. The start/stop characters A, B, C, and D can also be included on each bar code card.

• Interleaved2of5: This is a numeric-only barcode card type that must contain an even number of digits.

• MSI_Plessey: This variant of the Plessey barcode is capable of encoding the digits 0-9 and is variable length.

• PostNET: This numeric-only symbol is capable of encoding digits 0-9 and can be printed as a 5-digit PostNET barcode, a 9-digit Zip+4 PostNET barcode, or a 9-digit DPBC PostNET barcode.
