Hi Adeyinka,
It is possible to write additional information to a tag using the TracerPlus Software. Typically Information is written to two different banks on the RFID tag. The EPC bank, and the User Memory bank. The EPC bank is used to encode the Tag with a unique value. This unique value is typically used to identify a unique item and to ensure that this tag can be singled out against other tags.
The User Memory bank is typically used for additional information about the tag. It can be anything you like, a product description, a QTY, or even a serial number.
It sounds like you would want to write your additional information to this User Memory bank. The User Memory bank is different for every tag, so it is very important to know how much space you have, and if what you are planning on putting in there will fit.
Alternatively, if you know the information tied to a specific tag before hand it is possible to use TracerPlus Lookups to look up the more detailed information about the tag. It really depends on what you are looking to do, and which solution best fits your needs.
If you have any additional questions about this, please do not hesitate to ask.
