How to use the card reader

Take WINXP system as an example
First insert the memory card into the card reader. (Which position is inserted, everyone depends on the size of the card slot. The contact point can be determined anyway.) After connecting to the computer, it will be displayed in the lower right corner. New hardware (XP automatic installer), you will be prompted to use it after installation. The notification area in the lower right corner shows a small icon with a green arrow. Just put the things you want to install into the corresponding folder.　
note:
1　 Do not plug or unplug the card reader when reading data.
2　When uninstalling the card reader, be sure to close the page opened by the card reader, otherwise it may not be uninstalled.
3　 If you find that the page is closed, it still cannot be uninstalled. Open my computer and refresh it for a few times before uninstalling.
Audio UHF card reader
The card reader reads the corresponding device information in the electronic label
The reading distance is 1 meter (different tags have different reading distances)
Note: If the device is made of metal material, you should choose the anti-metal UHF electronic tag, but the distance of the reader to read the anti-metal electronic tag is shorter than that of the conventional UHF electronic tag.
The card device is connected with the audio port (earplug hole) of the smart phone; directly transmits the collected data to the smart phone through the audio interface;
The data collected by the card reader is transmitted to the smart phone through the audio port, and the smart phone is transmitted to the inspection system in real time through the CDMA1x network, and the inspection situation is tracked in real time and then processed.
Advantages: Long card reading distance, easy to carry.
Disadvantages: The card reader itself has no buttons, so you need to set a card reader button on your smart phone. For automatic card reading, you don’t need to set a card reader button.
