RFID读写器有两种主要的工作模式:被动模式和主动模式。在被动模式下,RFID芯片需要依靠读写器发送的无线电波信号来激活和传输数据;而在主动模式下,芯片可以自主发送无线电波信号,不需要依赖读写器的激活。被动模式具有较小的体积和成本,适用于物流追踪和库存管理等应用场景;而主动模式则更为灵活,适用于智能门禁和安全监...
RFID卡广泛应用于资产管理领域。无论是企业的办公设备、工厂的机器设备还是医院的医疗器材,都可以通过RFID卡进行标识和管理。通过RFID卡,企业和组织可以准确地追踪和管理所有的资产,减少遗失和损坏,提高资产利用率。 3. 出入管理 RFID卡用于出入管理系统中,可以实现对人员出入的控制和安全管理。通过将RFID卡绑定到员工或...
RFID(Radio Frequency Identification,无线射频识别)系统是一种通过无线电波进行自动识别和资料捕捉的技术。该系统主要由两部分组成:RFID标签和读写器。RFID系统可以在不接触物体的情况下实现快速、高效的识别和追踪,广泛应用于仓储物流、供应链管理、医疗、零售等领域。 RFID标签的工作原理 RFID标签是RFID系统的核心组成部...

Working Principle NFC doesn’t need any manual pairing or finding the device to share data like Bluetooth. By using this, two NFC enabled devices can be connected automatically in the four-inch specified range. The main advantage of NFC compare with Bluetooth is the shorter distance time. Becau...
IP cameras –PoE is now ubiquitous on networked surveillance cameras, where it enables fast deployment and easy repositioning. Wireless- WiFi and Bluetooth APs and RFID readers are commonly PoE -compatible, to allow remote locations away from AC outlets, and relocation following site surveys. ...
Ⅲ NFC working principle Ⅳ NFC working modes Ⅴ Comparison of NFC and other wireless technologies Ⅵ NFC applications Ⅰ Introduction NFC is developed on the basis of non-contact radio frequency identification (RFID) technology and combined with wireless interconnection technology. It provides a very...
These antennas normally operate based on theelectromagnetic inductionprinciple which means whenever RF energy is present then it generates an alternating magnetic field, which in turn induces a current within the loop, thus enabling the transmission (or) reception of signals. The current within the lo...
The main principle of operation of a transformer is mutual inductance between two circuits which is linked by a common magnetic flux. A basic transformer consists of two coils that are electrically separate and inductive, but are magnetically linked through a path of reluctance. The working principl...
