Matching the UID, RFID and Bar Code Technology to

There are a lot of individuals interested in RFID tags for various reasons and many early industry articles over-hyped RFID using the supposed nickel RFID tag. In addition, opinions tend to be slanted towards companies' main operations. As an instance, bar code companies will justify barcode since the most suitable choice whilst RFID businesses will warrant the newer technology of RFID as a superior solution. The emphasis has to be on effectively handling information, not on the true system to achieve this.


There are many methods of collecting and managing data: guide, magnetic stripe, OCR, barcode and, of course, RFID. What's the most practical method of gathering data for your own operation? Bear in mind that the newest emerging technologies aren't necessarily the best option. Maybe direct parts marking or barcode labeling is more practical and will provide the best return on investment. Evaluate all functional data collection methods and don't automatically predetermine a data collection method.


Environmental conditions not just ascertain the ID process, but also factor into the ID design. What type of impact will they have on the operation? We know that in high temperatures (>300°F) the prospects breakaway in the RFID inlay destroying the data. The quantity of exposure to UV, chemicals, and solvents usually decide the RFID tag design.


One more factor to consider is the anticipated read range for an ID product. Additionally, barcodes need to have a direct line of sight so as to be read where RFID tags don't. The read range for RFID tags is highly determined by the inlay utilized; nonetheless, in general terms, passive tags are going to have a read range up to approximately 20 ft.; in which active tags will expand read array beyond that.


The things being tracked are also a key factor in determining which technologies to use. Is your thing metal, wood, plastic, etc.? Manual methods or barcode work on nearly any surface condition without affecting readability; however, RFID reacts to various surfaces. Metal surfaces signify RF while fluids consume RF and in both instances will affect the readability of this label. When there are tag designs to help minimize the consequences of RFID on a metallic surface that layout might not be the best design for another surface, i.e. plastic.
