Introduction of non-contact IC card:
Non-contact IC card, also known as radio frequency card, consists of an IC chip and an inductive antenna, and is encapsulated in a standard PVC card. The chip and antenna have no exposed parts. It is a new technology developed in the world in recent years. It successfully combines radio frequency identification technology and IC card technology to end the problem of passive (no power in the card) and contact-free. It is the field of electronic devices. A major breakthrough. The card is close to the surface of the reader at a certain distance (usually 5-10mm), and the data is read and written through the transmission of radio waves.
Contactless cards have the following advantages:
⑴High reliability
⑵Easy to operate
⑶ Anti-conflict
⑷ can be suitable for a variety of applications
⑸Good encryption performance
Product packaging: single card packaging: manual or machine packaging (single sheet, multiple continuous sheets) can be selected, or the entire box package inner film can be selected
Single box packaging: Inner film or outer shrink film can be selected
Outer box packaging: Choose the corresponding outer box according to the transportation method and the number of cards, and pay attention to waterproof and pressure-proof.
Application range: Low frequency card is suitable for attendance system, access control system, property identification, process control, enterprise card system, parking, logistics,
Animal recognition, identity recognition, goods identification, industrial automation, conference sign-in, electronic tags, supermarkets, warehouse management, personnel management, security systems, medical institutions, etc. Stored-value cards, highway tolls, parking lots, community management, transportation logistics cards, medical cards, etc.
