Comparison of contact and non-contact electronic tags

Comparison of contact and non-contact electronic tags

  • 2020/01/06

In the data center U-bit asset digital monitoring and control plan, the communication methods of the U-bit asset module and the electronic tag are divided into contact communication and contactless communication.


Contact communication refers to the use of an EIC chip by inserting and removing the electronic tag to make the metal on the tag contact the contacts on the U-bit asset module, and then read the data.


Figure 1 is a partial enlarged view of the contact points of EIC technology products. It can be seen that the interface is worn due to plugging and unplugging.

Non-contact communication refers to electronic tags that read data in a polling manner through magnetic adsorption, mainly RFID chips.


Figure 2 is an RFID technology product that uses wireless data transmission without circuit contacts, adapting to a variety of harsh environments.
