Magnetic proximity cards are versatile tools used in various systems, ranging from access control to point-of-sale (POS) and time clock systems. These prox cards contain a strip of magnetic material that stores data. This data could include name, bank account, or other personal information. Once the prox card is swiped on a card reader, that card data will be read and then determine some form of authorization depending on the system and situation.
In access control systems, magnetic proximity cards are commonly used to regulate entry into buildings. When swiped through a card reader at an entrance, the system checks the card's encoded data against a database to verify the user's identity and grant or deny access. While more advanced prox cards have become popular for contactless access control, magnetic proximity cards remain a cost-effective solution for many businesses and organizations.
Magnetic proximity cards are also widely used in POS (point-of-sale) systems for processing transactions. Banks, for example, will encode payment information onto the magnetic stripe of your debit card which will then allow you to easily swipe your cards to make purchases. This makes magnetic proximity card technology essential for many businesses.
Additionally, magnetic proximity cards are often employed in time clock systems to track employee attendance. Workers can swipe their cards at the beginning and end of the day, allowing employers to record work hours with precise accuracy. This method is particularly useful in large corporations that have many employees to keep track of on a day-to-day basis. For example, this is commonly found at large retail stores, restaurant chains, and hospitals.
Despite the growing shift towards more secure technologies like prox cards and EMV chips, magnetic proximity cards continue to play a significant role in everyday systems. Magnetic proximity cards are easy to use and extremely cost effective.
