Proximity card readers are able to read people's cards, such as credit, debit, or Government issued cards. Proximity card readers carry a radio frequency chip which responds to other radio frequency chips, such as those in credit, debit cards and so forth, within a certain range. When these readers respond to the cards we have it tags them and they respond with an altered as signal. This allows the proximity readers to obtain personal encoded information such as names, social security numbers, phone numbers and important account information.
