Proximity is the name for contactless integrated circuit devices. Including either old 125 kHz devices or the newer 13.56 MHz contactless RFID cards, most commonly known as contactless smartcards. Not using a barcode or a magstripe the technology is securely stored within the card making it hard to copy or damage after constant use. Employees have the choice of cards, fobs or stickers with this technology.

Pros

• With Proximity actually imbedded inside a plastic casting i.e.a fob or card the technology is hidden from the elements meaning it is impossible to scratch or damage. It is also waterproof which means its application in extreme environments is also possible.
• There is no wear and tear between reader or card as the technology is contactless.
• To use proximity is quicker than all other technology such as Barcode, Pincode, Biometric or  Magstripe.
• All the data is encrypted so copying a card is impossible. Making it the securest solution available on the market.

Cons

• Proximity technology is still relatively expensive when compared to Bar Code, Pin Code, Biometric or Magstripe.
