In general, ID card yoyos are a frequently used method for attaching access cards, identification cards and access keys that are needed more often and must be handy.
Simply pull the cord and part of the cord is released.
So the key can be easily inserted into the door lock or the card held to a reader without annoying search.
Since the yoyo has no latching function, the rewind mechanism automatically retracts the cord cleanly and the key or ID card is again close, safe and if desired, visible on the body or in the pocket.
Whether opening a door by keys or smart cards or access control by readers or staff.The yoyo saves them the hassle of searching in their pocket and ensures them safe protection against loss or theft.Identification yoyos are versatile and very popular due to their ease and convenience of use.
