Types of Barcode Asset Tags

There are two main varieties of barcode asset tags: 2D and 1D barcodes.

1D refers to the kind of barcodes that supermarkets and shops have been using for decades – they encode everything from the International Standard Book Numbers (ISBNs) on the backs of books to the EAN and UPC codes we see on the backs of most consumer goods. There are several encoding protocols, like Code 128 and Code 39, each of which can be used to encode ASCII characters.

If you look closely at a bar code, you’ll notice a blank space on either side of the code, called the “quiet zone.” 1D barcodes have sets of “start” and “stop” bars that tell the scanner what direction to read the encoded numbers in – that’s why it doesn’t matter if you scan an item upside down. Inside “start” and “stop” are the numbers or characters that tell the scanning software what the item is. Sometimes (as in Code 128) scanners read those numbers in three-line sets; in code 39, characters are encoded in 5 lines and 9 spaces.

These types of barcodes can become unwieldy quickly, and are relatively error-prone, so for larger sets of characters or when accuracy is especially important, two-dimensional barcodes work better. There are dozens of types of 2D barcodes, including QR (or Quick Read) codes, which can be recognized by characteristic squares in three of their corners. QR has numerous advantages – it can be used to encode Japanese kanji characters, and it’s self-correcting, meaning that if 30% of a QR code has been removed, it can still be read – important for asset management when theft might be a danger! QR codes can be used to encode long character sets, send the scanner to a website, or even record a short block of text.

Tags themselves are as diverse as the materials they’re attached to. Some are tamper-evident, meaning they fall apart when a thief attempts to remove them. Annealed asset tags are softer than most, and can be used to durably mark surfaces that aren’t perfectly flat. To foil the truly dedicated crook, some asset tags are even flameproof. Plastic, aluminum and laminated tags are also widely available.
