Writable Tags ( RFID Writable Tags )

Pervasive computing is another term for ubiquitous computing. It’s a promising technology in the realm of ubiquitous computing, such as Radio Frequency Identification (RFID). Devices having a chip and antenna are known as RFID Tags, and they may be connected to (or implanted in) any item that can be read by an RFID reader. RFID tags don’t need a direct line of sight between the tag and the reader, and they may read and write at the same time. The majority of RFID tags are passive, which means they don’t need to be recharged, and they may last for many years without needing to be replaced.
RFIDs are capable of reading many tags at once, storing additional data on the tag, and manipulating the data on the tag. Additionally, the cost of adopting RFID technology is decreasing, which makes commercial implementation more feasible. The Electronic Product Code (EPC) is stored in the RFID tag, which is used to identify physical goods. These database files are accessible through a central network and provide additional information about the physical thing. The tag’s unique identifier (EPC) is used to get more information about the item from the network database. It is known as a data-on-network technique when an RFID tag and the corporate network are used together. The EPC is stored in a separate portion of the RFID tag’s memory. Electrically Erasable Programmable Read-Only Memory (EEPROM) makes up the extra memory on the tag. An example of this is the use of data on tags. This strategy relies less on a central database and more on the tags themselves to retain data. Data storage systems based on tags are therefore a kind of decentralized information storage.
