The application of RFID technology has a wide range and it can provide both convenience and security in specific areas. One of the most widely used RFID devices is the AS3990-BQFT, which is a device that makes use of a unique combination of technologies to provide both excellent performance and convenience. In this article, we will discuss the application field and working principle of the AS3990-BQFT.

Application Field
The AS3990-BQFT is a multiple function, multi-protocol three-channel RFID integrated reader which has a variety of applications. It can be used to facilitate access control, such as gate control, door control, warehouse monitoring or retail store management. It is also useful for RFID-tagged tools or equipment tracking, animal/personnel tracking, identification of food or medicine, and employee attendance management. In addition, many other applications are possible because of its flexibility.

Working Principle
The AS3990-BQFT is capable of reading and writing a variety of RFID tags, such as passive UHF Gen 2, NFC/Vicinity cards, and ISO15693 tags. It also supports many radio frequency protocols, including EPC Global UHF Class 1 Gen2, ISO 18000-6C, ISO18000-6B, ISO 18000-3M3, and NFC/Victinity. The device is powered by a low power 5V supply and has a wide variety of interfaces, making it possible to read and write a variety of RFID tags. Once the device is powered, it can read or write data from an RFID tag in the proximity of the device. This process happens by using radio waves to send out a signal that is detected by the reader and then interpreted.

The AS3990-BQFT is also able to detect other RFID tags in the vicinity of the device, thereby enabling it to be used as a monitoring IC. The reader can monitor the activity of a tagged object and use the data to generate alarms or trigger events. For instance, it can be used to trigger an alarm in case an unauthorized individual attempts to access a restricted area. The AS3990-BQFT can also be used in highly sensitive areas like airports and other secure facilities, as it is capable of detecting any illegal activity involving RFID tags within its proximity range.

All in all, the AS3990-BQFT is a highly versatile device that can be used in a wide variety of applications. It is capable of reading and writing multiple types of RFID tags, as well as monitoring activity within its proximity. This makes it an excellent choice for access control, RFID tracking, and monitoring in general environments and secure facilities alike.
