👉 A collarless device is a device that does not have any external connections or connectors to communicate with other devices. It is usually used in situations where there are no wires, cables, or other means of communication available. Examples include smartphones, laptops, and some types of computers. Collarless devices can be useful in scenarios where physical connection is difficult or impossible, such as remote work, medical equipment, or even when the user needs to communicate with a device that cannot be physically connected to a computer
