![]() Direct-attached (including PAN/Bluetooth) RFID+NFC reader hardware: No (because OS services/syscalls aren't available in Blazor).NET libraries from within Blazor (so not calling in-browser JavaScript APIs from within Blazor) Internet/LAN website or PWA using C# code and. ![]() Infrastructure scanners/readers with HTTP-based web-services: Yes, provided you can access them using fetch/ XMLHTTPRequest, EventSource or WebSocket.USB/COM: Presently no as WebUSB support is disabled in Chromium-based browsers and no other browsers support it.(Also note that Bluetooth LE and "normal" Bluetooth are very different despite sharing the "Bluetooth" brand). Bluetooth: Potentially, provided you use the Web Bluetooth API, it depends on hardware and browser support.Direct-attached (including PAN/Bluetooth) RFID+NFC reader hardware:.Internet/LAN website or PWA using in-browser JavaScript APIs: Some RFID hardware vendors (both system-integrators and actual hardware OEMs) provide infrastructure-based readers/scanners (the kind that are permanently mounted on a wall or ceiling) that provide HTTP-based web-services (SOAP, REST, something else, etc) that your Blazor code could also use. However, in a few years, if browser vendors add support for proposed JavaScript APIs for NFC and RFID hardware ("Web NFC") then you could use the those APIs from your code. NET assemblies that work with common RFID and NFC hardware over local communication ports (COM, USB, Bluetooth, etc), then no, it is not possible. Review the evolution of RFID.įor more information about how RFID works and how to integrate this technology into your business processes, read our RFID Basics.Assuming you're referring to using desktop PC. ![]() In addition, RFID tags are not susceptible to the damages that may be incurred by barcode labels, like ripping and smearing.įrom the read distance to the types of tags available, RFID has come a long way since World War II and there is a bright future ahead. RFID offers many advantages over the barcode, particularly the fact that an RFID tag can hold much more data about an item than a barcode can. Whether or not RFID compliance is required, applications that currently use barcode technology are good candidates for upgrading to a system that uses RFID or some combination of the two. Department of Defense (DoD)and Wal-Mart requiring their suppliers to enable products to be traceable by RFID. Smart labels can be encoded and printed on-demand using desktop label printers, whereas programming RFID tags are more time consuming and requires more advanced equipment.Īlthough RFID technology has been in use since World War II, the demand for RFID equipment is increasing rapidly, in part due to mandates issued by the U.S. They’re made of an adhesive label embedded with an RFID tag inlay, and they may also feature a barcode and/or other printed information. Smart labels differ from RFID tags in that they incorporate both RFID and barcode technologies. For a more detailed discussion, refer to this article: Passive RFID Tags vs. Unlike passive tags, active RFID tags have an onboard power supply (e.g., a battery), thereby enabling them to transmit data at all times. Passive tags must be “powered up” by the RFID reader before they can transmit data. Passive tags are the most widely used, as they are smaller and less expensive to implement. RFID tags come in a variety of shapes and sizes and are either passive or active. ![]() For example, employee ID badges containing RFID tags are typically made from durable plastic, and the tag is embedded between the layers of plastic. The protective material depends on the application. The tag is also composed of a protective material that holds the pieces together and shields them from various environmental conditions. As stated above, an RFID tag consists of an integrated circuit and an antenna.
