1. You can sign in with your mobile phone when you enter the venue, and you can also use the 31 WeChat wall to interact in the venue. You can post, speak, and send photos.
2. There is a sign-in method suitable for thousands of people's meetings: WeChat QR code sign-in, which means that participants only need to scan the QR code to sign in without queuing up.
3. For example, internal fixed personnel such as companies, institutions, school units, etc. can use the original fingerprint weaving and magnetic card recognition system, and the peripheral identification collector in the venue can be transmitted to the attendance system, and thousands of people can have no pressure;If it is a non-fixed person, you can use the barcode, 3D code and magnetic stripe in the invitation letter to pre-record and issue it, and use the identifier to enter and record it on the spot.
4. Yes, you can try Xiaowei's interaction. As long as the participants scan the QR code provided by the event party, the sign-in is successful. It is very convenient. Just guide the personnel to guide the participants to scan the code.
5. Learn to record the minutes of the meeting with mind maps, which is fast and fast to sort out. To improve the speed of meeting minutes, it can generally be divided into five points: fast, save, need, substitute, reasonable.
6. I) Common methods: This kind of meeting can prepare the badge to be used by the participants in advance and mail the badge to the participants according to the address provided by the participants. Advantages: The on-site management will reduce the check-in time when the participants enter.
1. That is the radio frequency card, inside The coil plays the role of receiving radio frequency signals and feedback data sent by the punching machine and providing power for the card.
2. According to the law of electromagnetic induction,As shown in the figure: (2) Electromagnetic reverse scattering coupling: radar principle model, the electromagnetic waves emitted are reflected after hitting the target, and carry back the target information at the same time. Based on the spatial propagation law of electromagnetic waves, the inductive coupling method is generally suitable for near-range radio frequency identification systems for medium and low frequencies.
3. The basic principle of radio frequency technology refers to a circuit in which the electromagnetic wavelength of the processing signal is in the same order of magnitude as the circuit or device size. At this time, due to the relationship between the device size and the wire size, the circuit needs to be processed with the relevant theory of distribution parameters.
4. The working principle of the RFID system In the actual application of the RFID system, the electronic tag is attached to the surface of the object to be identified, and the electronic data in the agreed format is stored in the electronic tag. The reader can read and identify the electronic data stored in the electronic label without contact, so as to achieve the purpose of automatically identifying objects.
5. And the technology of automatic recognition through the transmitted information, its working principle and process are summarized as follows. The radio frequency signal and spatial coupling transmission characteristics are used to realize the automatic recognition of the recognized object, and the spatial (non-contact) coupling of the radio frequency signal is realized between the radio frequency tag and the reader through the coupling element.
There are two main forms of handheld readers. One is an RFID reader with a barcode scanner, which can scan and read both barcodes. Take the RFID tag. Another is an RFID reader installed on a PC card, which is embedded in the PCMCIA of a laptop or handheld computer.
At the same time, the contactless interface can realize contactless consumption, access control, attendance and other applications.
In addition, RFID technology can also be applied to laboratory security control. For example, RFID tags are used as access control cards. Only people with valid RFID tags can enter specific areas to ensure the safety of the laboratory. Extended supplement: RFID tags have a wide range of applications.
Non-intelligent RFID card identification technology uses RFID radio frequency technology for identification, which can identify the corresponding information data under different distance environmental conditions.
The action distance of the low-frequency RFID card is less than 10cm. Low-frequency card refers to a card with a frequency of 100-125KHz, with a typical value of 125KHz, HID, EM technology, etc., which are common in the market.Low-frequency cards are mainly used in attendance access control, hotel door locks, animal labels, product production management, etc.
