What is a device that is around the same size as a credit card, containing embedded technologies that can store information and small amounts of software to perform some limited processing?

Smart card

Explanation:

A smart card looks much like a credit card in shape and size, but it is very much different inside. A smart card usually have an inside, but a credit card is simply plastic in nature. Inside a smart card we can find a microprocessor embedded within. It is usually located beneath a gold contact pad found on a side of the card. The microprocessor is capable of storing information and they are usually used in limited processing.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
