smartcard controlled relay

smartcard controlled relay

The door opens inserting an electronic card! Very useful also to access private parks, enable photocopiers, activate showers and night light in sport resorts shared between clubs.
This design uses a smart card to enable a relay. A Nutchip recognizes its mating smart card among thousand similar ones, because you choose the code to be programmed in the card’s memory. No speacilized knowledge is necessary, as we supply the card program and codes. Nutchip truth table is simple as well, so you should be able to adapt it to your needs (e.g., adding more than one card, or timing the relay). Even in its actual form, the board is ready to work in many useful applications:

open gates e.g. for park lots…

access control to gyms, swimming pools, tennis play fields…

switch on central heating or showers, or the football field lights…

enable TV viewing, photocopyng, faxing, coffe machine use, telephones etc.

Smartcards are very handy as they are compact, lightweight, and require no batteries. Cards are tough compared to remote controls, are resistant to dirt and wet, and don’t break apart falling from a tabletop. If a card gets lost or stolen, you can reprogram the Nutchip in minutes, discarding the old code in favour of a new one, therefore making the old card useless.
