Barcode Card Types

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.

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.

UPC-A: This fixed-length, numeric-only symbol must contain 12 digits. The first eleven digits are supplied by the customer. The twelve “check digit” is a calculated number based on the preceding numbers.

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.

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.

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

Security: RFID has long been used as an electronic key to control who has access to office buildings or areas within office buildings. The first access control systems used low-frequency RFID tags. RFID tags can also be combined with motion sensors so that when objects are moved without authorization, an alarm is sounded. RFID tags can be put on laptops and files containing sensitive documents to make sure they are not removed from a building without authorization.
