- RFID tag form factor
- Points of visibility
- Software and middleware application
The tag form factor has to do with the physical aspects of the application. Aspects such as, type of tag, data capacity requirements, and desired read rates, a metric for system performance. Usually depending on the material to be tagged with RFID it's important that the form factor of the tag is taken into account . Well written specs of the operating conditions and the flow of the assets are required. the understanding of how the tag will applied to the assets whether the tags will be enclosed protective pockets or plastic or will be attached to a metal surface define a lot of the decisions in the RFID install. These physical aspects are of utmost importance for the reliability of the system.
The points of visibility are related to the RFID reader or access points that will collect the data. Usually a site survey has to be performed and spectrum analysis it is highly recommended to minimize the risks of interference and poor read rates. The quality of the reader is extremely important and the specs of the readers have to be accounted for to make sure the reader will fulfill the applications performance and constraints. Reader should be EPC compliant so that the industry standard can be used for any RFID tag vendor
Last but no least the middleware or software that will display the data is the defining factor to have a full deployment successfully running. There are several vendor and integrators and it is recommended that prior to contract or purchase any software, a good look is taken to the flexibility of the software to minimize expenses on complex integrations or software with too many or little features.
In summary these are the three aspects that should be considered closely prior to any RFID install or use of the technology in a data collection context.
