RFID Tag

(noun)

Wireless tags with electromagnetic fields to transfer data, for the purposes of automatically identifying and tracking tags attached to objects.

Examples of RFID Tag in the following topics:

  • Antennae

    • These include: radio broadcasting, broadcast television, two-way radio, communications receivers, radar, cell phones, and satellite communications; as well as other devices such as garage door openers, wireless microphones, bluetooth enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise.

  • Project Management Inventory

    • RFID Tags - RFID (radio-frequency identification) tags are used to track the locations of various items, from components in an automobile assembly line to boxes of cereal shipped from a manufacturing plant to the grocery store.
    • These little tags communicate vast arrays of location data to inform timing processes and ensure proper inventory levels.
    • This image illustrates the information flow of RFIDs, which is then streamlined into large data streams for PMs to track.

  • When innovation fails: deleting products

    • For instance, Wal-Mart has introduced new logistical technologies such as radio frequency identification (RFID) to optimize its logistic processes.
    • RFID is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.

  • Purifying Proteins by Affinity Tag

    • Tags are attached to proteins for various purposes.
    • The poly (His) tag is a widely-used protein tag; it binds to metal matrices.
    • Epitope tags include V5-tag, c-myc-tag, and HA-tag.
    • Protein tags are also useful for specific enzymatic modification (such as biotin ligase tags) and chemical modification (FlAsH) tag.
    • This is to prevent the polyhistidine tag from affecting the activity of the protein being tagged.

  • Mechanics of Release Branches

    • When the release branch is stabilized and ready, it is time to tag a snapshot from the branch:
    • That tag now represents the exact state of the project's source tree in the 1.0.0 release (this is useful in case anyone ever needs to get an old version after the packaged distributions and binaries have been taken down).
    • The next micro release in the same line is likewise prepared on the 1.0.x branch, and when it is ready, a tag is made for 1.0.1.

  • The Golgi Apparatus

    • Before reaching their final destination, the lipids or proteins within the transport vesicles still need to be sorted, packaged, and tagged so that they wind up in the right place.
    • Sorting, tagging, packaging, and distribution of lipids and proteins takes place in the Golgi apparatus (also called the Golgi body), a series of flattened membranes .
    • These newly-modified proteins and lipids are then tagged with phosphate groups or other small molecules so that they can be routed to their proper destinations.
    • Finally, the modified and tagged proteins are packaged into secretory vesicles that bud from the trans face of the Golgi.

  • Warehousing

    • Warehouse management systems often utilize Auto ID Data Capture (AIDC) technology, such as barcode scanners, mobile computers, wireless LANs and potentially radio-frequency identification (RFID) to efficiently monitor the flow of products.

  • The FISH Technique

    • The probe can be tagged directly with fluorophores, or with targets for flourescently labelled antibodies or other substrates.
    • Different types of tags can be used, therefore different targets can be detected in the same sample simultaneously (multi-colour FISH).
    • Tagging can be done in various ways, such as nick translation, or PCR using tagged nucleotides.

  • Prevent Territoriality

    • At the Apache Software foundation we discourage the use of author tags in source code.
    • There is no clear line for when to add or remove an author tag.
    • Do you remove other author tags when you refactor the code and it looks 95% different?
    • Author tags also tend to get out of date.
    • First, the tags inevitably raise the awkward question of how much work one must do to get one's own name listed there too.

  • Plasmids as Cloning Vectors

    • Protein purification tags: Some expression vectors include proteins or peptide sequences that allows for easier purification of the expressed protein.
    • Examples include polyhistidine-tag, glutathione-S-transferase, and maltose binding protein.
    • Some of these tags may also allow for increased solubility of the target protein.
    • The target protein is fused to the protein tag, but a protease cleavage site positioned in the polypeptide linker region between the protein and the tag allows the tag to be removed later.
