In the modern world where security and convenience are both necessary, there are new technologies that have been developed to make lives easier for companies, consumers, employees and almost all parties involved. The advent of barcodes and radio frequency identification or RFID has made it easier to assure security and ease of transactions. There are barcode tags and scanners that are widely used in the most frequented establishments, while RFID tags and scanners make it easier for more sophisticated modern transactions to get done easily.

Barcode tags and scanners are so common nowadays. If you drop by the grocery, the department store or the record bar, you would notice that cashiers do not have to manually key in tag prices of commodities when charging the customer. Instead, cashiers make use of barcode tags and scanners that are installed in their posts. Notice that products have barcodes in their labels. And the machines used by cashiers are devices that can read encoded messages and data within those barcodes. Thus, barcode tags and scanners have rapidly become necessities in the retail and department store chain industries.

On the other hand, RFID tags and scanners are useful in areas and industries where barcodes tags and scanners can function with limitations. RFID tags and scanners use transponders that read remotely stored data on chips incorporated into products, animals and even persons. The technology rely on the use of radio waves for transmitting and retrieving data, different from how barcode tags and scanners use simple data identification and deciphering methods. Thus, RFID tags and scanners are useful even if the chips or objects are far from each other.

RFID tags and scanners are currently useful in transportation and toll payments, animal identification, passports, product tracking and in schools and universities. Some people also consent to human implanting of tiny and negligible chips within certain areas of the body so that RFID tags and scanners can be used to track them or identify their presence anywhere needed.

Many technology aficionados are eyeing RFID tags and scanners as possible and effective replacements and alternatives to barcode tags and scanners. That is because the former have numerous advantages that make them far better and more useful than the latter. However, analysts and market observers note that RFID tags and scanners will completely takeover the roles of barcode tags and scanners in the future, that is if costs would be minimized. RFID technology is currently more expensive. Thus, not too many businesses and institutions readily adopt them.

The future of such codes is very much rosy. Because of the eagerness and excitement both of people and businesses to adopt such high technologies, it is imaginable that soon people can enter buildings, pay bills and make transactions base don their own and personal identification. That way, transactions would be made easier, faster, more accurate, more convenient, and mostly, more secure.
