Proximity Cards (or 'Prox Cards' as they are commonly known) sprang to life in the 1990s and are still very common today in largely physical access control systems or identification applications. 

Prox Cards are contactless cards operating at a frequency of 125kHz. As this is a relatively low frequency, this limits the amount of data that can be transmitted up to 64 bits normally resulting in one-way communication between a card and a reader. 125 kHz Prox Cards are less affected by other radio signals and materials in the environment such as water or metal which makes them a reliable choice in industrial environments.

Popular brands include HID Prox, Indala, EM4102, Hitag 1, Hitag 2, Hitag S256, Hitag 2048 and compatible brands like Swiftprox.
