The difference between ID wristbands and ID wristbands

Update time:2023-04-03 16:07:07 / Views:106

ID wristbands are developed on the basis of RFID. ID wristbands are not very different from RFID in essence, they are based on the signal transmission between two objects in close geographical proximity.

The difference between ID wristbands and ID wristbands

But ID wristbands and RFID or there are differences, ID wristband technology adds a point-to-point communication function, you can quickly establish a Bluetooth device between the P2P (point-to-point) wireless communication, ID wristband devices to find each other and establish a communication connection. p2p communication between the two sides of the device is peer-to-peer, while RFID communication between the two sides of the device is the master-slave relationship.

There are some remaining technical details:

ID wristband compared to ID wristband RFID technology, has a number of features such as close distance, high bandwidth, low energy consumption. Details are as follows:

1, ID wristbands are only limited to the 13.56MHz band, while the RFID band has a low frequency (125KHz to 135KHz), high frequency (13.56MHz) and UHF (between 860MHz to 960MHz).

2, the effective working distance: ID wristband (less than 10cm, so with high security), RFID distance from a few meters to dozens of meters are available.

3, because the same work in 13.56MHz, ID wristbands are compatible with existing contactless smart card technology, so many manufacturers and related groups support ID wristbands, and RFID standards are more, unified more complex, only in special industries with special needs, using the appropriate technical standards!

4、Application: RFID is more often used in production, logistics, tracking, asset management, while ID wristbands play a huge role in access control, public transportation, cell phone payment and other fields.
