What is an RFID Tag Reader?
RFID stands for Radio-Frequency Identification. An RFID Tag Reader is basically a technology that helps to encode digital data present in RFID tags or smart labels that are captured by a reader via radio waves. RFID is fairly similar to barcoding wherein the data from a tag or a label is captured by a device that has data stored in a database.

The RFID Tag Reader, however, holds a bunch of advantages over systems that use the barcode asset tracking software. The most important and well-known one being that the data from the RFID tag can be read outside the peripheral vision of the scanner, whereas on the other hand, the barcodes must be aligned properly with the optical scanner.

It is easy to find an RFID Tag Reader in Mumbai and you can definitely set them up on your own using the manual.

How does it work?
The RFID belongs to a group of technologies called Automatic Identification and Data Capture (AIDC). The AIDC follows a method that automatically recognises objects, gathers data about ...
... them, and enters those data directly into computer systems without any manual intervention. The RFID methods also utilize radio waves to accomplish this.

In simple words, the RFID systems consist of three components: an RFID tag or smart label, an RFID reader, and an antenna. The RFID tags contain a combined circuit and an antenna, both of which are used to transfer data to the RFID reader, which is also called an interrogator. The RFID reader then converts the radio waves into data that is usable, and this acquired information from the tags is then transferred via an interface of communications to a host computer system, where the data is then stored in a database and is allowed to be analyzed subsequently.

What are RFID tags and Smart labels?
The RFID tag has an integrated circuit and an antenna and is composed of a guarding material that holds the pieces together and shields them from different environmental conditions. The protective material depends on the application. RFID tags also come in a plethora of different shapes and sizes and are also either passive or active. The passive tags are the most widely used ones, as they are rather concise and inexpensive to execute. They must, however, be “powered up” by the RFID reader before they start the process of transferring data. On the other hand, the active RFID tags have an onboard power supply, which enables them to transfer data whenever in use.

Smart labels are very different from RFID tags in the sense that they incorporate both technologies, i.e. RFID and barcode technologies. The smart labels are made of an adhesive label secured with an RFID tag inlay. They also feature a barcode with some more information printed on it.

The biggest difference between the two labels is that smart labels can be encoded and printed on-demand using just a desktop label printer, on the other hand, the RFID tags consume more time to print as they require highly advanced equipment.
