The tyvek wristband is embedded with a  chip, which is embedded in the interlayer of the tyvek. Since the tyvek itself is waterproof and tear-resistant, it can well protect the chip from being damaged. The chip in the tyvek   wristbands enables the tyvek wristband to have the function of identification. Now many large-scale commercial events such as concerts, tyvek wristbands have played a role in the security of the event, and greatly reduced the workload of the staff.
