Which Applications Need High Memory RFID Tags?

Introduction
If you're looking to incorporate an RFID system, you might be wondering about RFID tags and how much memory your application will require. Below is information regarding which applications typically require high memory RFID tags.
Answer
The best way to answer this question may not be necessarily to call out specific applications that may (or may not) need high memory - for example, asset tracking, etc. Rather, a better way to determine if an application needs high memory RFID tags, is to determine if the application will be able to have reliable access to a database (as needed) in order to pull up relevant information about the tagged object.
Because a database can theoretically store as much information as required about any given tagged object, as long as the user has access to that database, the only thing a tag really needs is a unique ID within that application. In such a case, the user would simply read the RFID tag and then be able to pull up as much information as needed (assuming the user interface is designed accordingly). The database access could occur in real-time if the RFID reader is connected to a network, but can also occur if, for example, a user has a mobile RFID handheld reader that has a local copy of the database. (In this example, the local database would need to periodically sync with the master database.)
In the event that reliable database access isn't possible and the user must store data about the tagged item, then storing data on the tag itself may be the best option and this is when high memory RFID tags would be needed.
