Identification techniques are methods used to determine the identity of a person, object, or substance. Common techniques include fingerprint analysis, DNA profiling, and facial recognition. These methods rely on unique characteristics that can distinguish one individual or item from another, making them essential in fields like forensics, security, and biology. In addition to biological methods, identification techniques can also involve the use of technology, such as barcode scanning and RFID tags. These tools help track and identify products in retail and logistics. Overall, identification techniques play a crucial role in enhancing safety, security, and efficiency across various industries.
