Touchlink

Touchlink is a technology that allows for wireless data transfer and device communication through physical contact. When two devices equipped with Touchlink technology are brought into close proximity, typically by touching them together, a secure and rapid data exchange can occur. This method leverages near-field communication (NFC) principles, but the specific implementation and protocols can vary between different manufacturers and applications.

The primary advantage of Touchlink is its simplicity and the inherent security it provides due to the short-range nature of the connection. It eliminates the need for manual pairing processes like Bluetooth or Wi-Fi setup. Common applications include quick payment transactions, sharing contact information, transferring files between devices, or initiating device pairing for more complex wireless connections. The speed of data transfer can vary, but it is generally sufficient for small data packets and commands. While the term "touchlink" may be used generically, specific implementations often have brand-specific names.
