The Qsignalmapper of QT The Qsignalmapper of QT Briefly On the Code Related Knowledge points article End Briefly Qsignalmapper we can understand it as a transponder, what do we say? For example, the button clicks the response slot, binds to the Qsignalmapper, Qsignalmapper receives the button the click, and notifies the other control to do the processing. Some friends will ask, why so tr

) three major components. Reader: The device that reads or reads/writes the electronic tag information, the main task is to control the RF module to transmit the reading signal to the label, and receive the response of the label, decode the object identification information of the label, and transmit the other related information of the object identification information and tag to the host for processing. Antenna: A transmitting and receiving device for transmitting data between a l

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 Passive Tag uses the radio waves sent by the reader as the power to start the IC circuit. Therefore, it has the advantage of semi-permanent use, but the communication distance is shorter than that of the active tag. On the other

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 be selected based on the communication distance. Currently, antenna materials include al

× 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

The worry about RFID security is not new. However, these concerns grew when the US MRT company and Chase started issuing RFID-enabled credit cards last year. The fear escalated when researchers at the University of Massachusetts announced in October this year that they had breached the credit card RFID security feature. RFID
