1.

2, the bus IC card is a contactless data card, the principle is based on the interaction of the chip integrated in the card and the inductor. Inductor coil is wound by copper wire, its two ends through the circuit to form inductive current, and then converted into direct current. Then, straightThe current is incorporated into a relatively large capacitor to keep the voltage stable at both ends. Then, the signal transmission line from both ends of the inductor is connected to the chip.
3, it is integrated in the card chip through the inductor coil on the card, at both ends of the coil through the action of various circuits to make the induced current into DC, and then from both ends of the DC into a relatively large capacitor, can make the voltage at both ends remain stable, at both ends of the coil and then lead two lines to the chip, as a signal transmission line. When approaching the card reader, the coil generates an induced voltage, which can realize the transmission of data between the card and an external database.A

5, · The watermelon in your arms - sure (metaphor is very accurate or sure) · A hundred feet high pole hanging red light - outside to see the inside red (metaphor surface is wrong, in fact, not) · a hundred years old son - rare (metaphor is not easy to get orYes.
Can be used, the IP of the wireless network card is not allowed, I use the wireless network card, there is a period, buy once a year, you use it, the expiration will automatically stop. You can't find the owner if you don't have to.
He's right. Unless there is a GPS positioning function, the basic listed laptop computers are not available.
Make sure they've reported it lost, thenTelecom shut down the card. You can apply for a wireless broadband package at Telecom.
Simple, the number of the wireless network card is lost on the Internet, you can find the network card owner.
No password, you know it's no use. Plus, the owner probably already reported the lost card.
