Signatures

When I'm in school I start to learn how to sign on papers as to represent me when needed. Signature identify the person.

Fill in the application forms,  issuing a cheque, using credit cards,  and others that need to put indicator that it is mine.

Another example is my car. Car plate number is unique and also represent me. Now days car models do have something that represent their model. We can identify the car model from the brand and design. During day time it is easy to recognise it but at night it is difficult to know what is the car model from distance and I notice that now many cars have their signature to identify the car model at night using their front and tail light.

Signature is very useful to identify someone or something. ..I think so
