Proximity Card

iPROXIMITY CARDS 125 Khz RFID Cards

Proximity cards, alsoi knowni as proxi cards,i are lowi frequency 125 kHzi credentials that feature  an  embedded  metallic antenna coil that stores cardholder data.
Data stored on a proximity card key fob or tag can be detectedi by reader when thei proximityi card isi passed within range.

proximity card or proxy card is a "contact less  smart cardi i which cani ibe read withouti inserting it into a reader device
as required by earlier magnetic stripe cards such as credit cards and contact type smart cards The proximity cards are part of the contact less card technologies.
Held near an electronic reader for a moment they enable the  identification of ani encoded number.
The reader usually produces a beep or other sound to indicate the card has been read. Proximity cards typically have a read range up to 50 cm 15 inches
which is the main difference with contact less smart card with 2 to 10 cm 1 to 3 inches . The card can often be left in a wallet or purse
and read by simply holding the wallet or purse near the reader.i The term proximity cardi refers to the older 125kHz devices as distinct to the newer 13.56MHz
contact less smart cards.

Method of operation

The card and the reader unit communicate with each other through 125kHz radio frequency fields,
13.56MHz for the contact less smart card cards by a process called resonant energy transfer Passive cards have three components
sealed inside the plastic an antenna consisting of a coil of wirei a capacitor and an integrated circuit IC
which contains the user's ID number in specific formats andi no other data. The reader has its own antenna
which continuously transmits a short range radio frequency field.

When the card is placed within range of the reader, the antenna coil and capacitor, which form a tuned circuit, absorb and store energy from the field,
resonating like an electrical version of a tuning fork. This energy is rectified to direct current which powers the integrated circuit.
The chip sends its ID number or other data to the antenna coil, which transmits it by radio frequency signals back to the reader unit.
The reader checks whether the ID number from the card is correct, and then performs whatever function it has been programmed to do.
Since all the energy to power the card comes from the reader unit, passive cards must be close to the reader to function, and so have only a limited range.

Proximity cards also known as proxy cardsi are lowi  frequency 125 kHz  credentials that feature ani embedded metallic antenna coil that stores cardholder data. Data stored on a proximity cardi key fob ori tag can be detected by ai reader when the proximity card is passed within range.i

A proximity card or proxy card is ai contactless smart card which can be readi withouti insertingi it into a reader device as required by earlier magnetic stripe cards such as credit cardsi and contact typei smart cards.i The proximity cards are part of the contactless card technologies.

The card can often be left in a wallet or purse and read by simply holding the wallet or purse near the reader.
