The most universally found in our daily life is barcode. Almost any quality-guaranteed product has barcode. It is not only as signal, but also a mind relief making customers feel ease for what they have brought is real and reliable. There is no doubt that products cannot live without barcode any more. Where there is a product, there is a barcode. And barcode labels are derivatives of barcode.

Today, barcodes such as the UPC have become a ubiquitous element of modern civilization, as evidenced by their enthusiastic adoption by stores around the world; almost every item other than fresh produce from a grocery store, department store, and mass merchandiser has a UPC barcode on it. This helps track items and also reduces instances of shoplifting involving price tag swapping, although shoplifters can now print their own barcodes. But some commodities like garments or drinks that are hard to have barcode printed on, at this time, barcode labels are urgently needed. They are available attached to those products, showing them reliable and up to standard. Nowadays barcode labels are not just a signal showing relevant hidden information about products, but playing such an essential role in preventing products from being stolen.

For instance, barcode labels can be applied for patient identification (to access patient data, including medical history, drug allergies, etc.) to medication management. The application of barcode labels help doctors save a great deal of time to track records and make patients’ conditions clearly seen to some extent. Recently barcode labels have become an indispensable part in every aspect of our life. No matter garment industry, medical industry, military industry and so on, barcodes can be seen everywhere and paid greater attention. The outlook is promising and worth expecting.
