RFID or Radio Frequency Identification is the new technology for product identification and data storage that can be used where the barcode failed. It is based on the same concept as barcodes, except that different data encoding methods for optical scan barcodes require a line of the eye.
RFID tags fall into two categories, active or passive. Active tags have an internal battery with read and write options, which allows modification of data. The memory size of the tag is variable with some tags having a memory space of up to 1 MB.
Passive RFID tags do not have an external power source and instead use the power generated from the reader. For more details about RFID inlays and label, Visit here http://www.sunhingprinting.com/en?o=2&c=3

RFID passive tags are programmed with a particular set of data that can not be changed and be read-only, they operate as a plate in the database. Passive RFID tags have a low-power integrated circuit attached to the antenna and are used to attach the protective packaging depending on the application will be used for.
These tags are also called inlays and transponders. In technical terms, it is simply a tag inlay on flexible substrates ready for conversion into smart labels. Smart labels can extend the basic functionality by combining RFID technology barcode and human-readable information.
They include adhesive labels embedded with an RFID tag inlay to provide benefits read range and unattended capabilities of the tag, with the flexibility and convenience of on-demand label printing.
