RFID belongs to a group of technologies referred to as Automatic Identification and Data Capture (AIDC). AIDC methods can identify objects automatically, collect data about them, and enter those data directly into computer systems with little or no human intervention.
RFID methods utilize radio waves to accomplish this. At a simple level, RFID systems consist of three components: an RFID tag or smart label, an RFID reader and an antenna. RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data. Information collected from the RFID tag is then transferred through a communications interface to a host computer system, where the data can be stored in a database and analyzed at a later time.
Though the RFID technology has evolved considerably, the barrier to adoption seem to remain the same. That’s why you have to know common mistakes of using RFID products.
1. Selecting the Wrong RFID Tag(s)
This may sound very basic but many new people to RFID think RFID tags like bar codes, but in reality, there are big differences. For example: just because you see a RFID tag doesn't mean your RFID equipment will see it. Contrarily, if you can't see the RFID tag, it doesn't mean your RFID equipment won't read it. Many people even try to use a hand-held RFID reader like a bar code gun and don't realize they are reading RFID tags because there's no light coming from the front of the reader. My point is: RFID is still new to many people and different RFID tags have different performance.
For the record: UHF RFID tags work on metal and can be read in water! You just need to know which combine of RFID tags, antennas, and readers to use.
First of all, you should understand how the RFID tag works, where to place the RFID tag on what you're trying to track, what RFID tag you should use, and the cost of RFID tag.
2. Do not consider All the Angles
Some RFID tags are designed to be read by a specific type of antenna or from a consistent read angle. In material handling and automated work-in-process applications, it is relatively easy to control the RFID tag and reader locations. In many other operations, this is not the case, so the RFID tag will need more read angle flexibility.
3. Have not planed for the complete life cycle before use them
Try to plan the entire life cycle of RFID tag. The person who scans an RFID tag will not be exposed to extreme temperatures, but the tag may. Besides temperature, consider the storage, handling and cleaning processes that tags will encounter, as well as exposure to chemicals, radiation, moisture and other environmental conditions.
Knowing these aspects, I believe you can avoid common mistakes in using RFID products.
