rfid tags for inventory

According to the internal structure of RFID tags, they are divided into active tags with battery (Tony Note: Also called active tags) and passive tags without battery (Tony Note: Also called passive tags) these two types. The Pass

Antennas are rectangular, circular, and rod-shaped. Generally, the longer the communication distance is, the larger the size of the antenna. However, in actual use, when tags are attached to an item, even the RFID tags of the business card size are too large. In fact, the size and shape of the RFID tag in use need to b

× Winding Process It is a process that combines an antenna and an IC loop to form a module. It takes some time to mount modules one by one on a thin board. Therefore, high costs are not suitable for mass production. However, compared with other manufacturing processes, the tag communication distance is improved. × Etching ProcessIt is a process of forming an antenna by etching aluminum or copper film on the pet Film Board. Figure 4 shows an item (using an etching antenna in an IC circuit). B

For an RFID system, the concept of Frequency Band refers Frequency Range of tag signals sent, received, and read by the reader through an antenna . In terms of application concept, the operating frequency of the RF tag, that is, the operating frequency of the RFID system, directly determines all aspects of the system application. In an RFID system, the system wor

The Passive Tag does not generate electricity itself, but uses the radio waves sent by the reader as the power of the IC circuit. This is divided into two types: the induction mode and the electric wave mode (Figure 3 ). Electromagnetic Induction: receives the time-varying magnetic field from the reader through a ring antenna to provide power to the IC circuit. This is the same principle as a turbine generator (Tony Note: How is a turbine generator working? ). Radio waves: In order to effect

In XHTML or HTML4, we will see code similar to the following:0105Div>08Div>Ten 11Div>14Div>Div>Now I see the following code look:01Geneva 05Header>08Section>Ten 11Section>14Footer>Section>Intuitively, the above example is wrong: not a container. Elements are semantic sections that help build a document outline. It should contain a caption. If you are looking for an element that can contain a page (whether HTML or XHTML), it is common practice to def
