at 125 khz, you will not have a real antenna, the size would be prohibitive. the best you can hope for is an inductive pickup. a coil on a ferite bar would work fine. check amidon associates for ferite antenna material.

RFID Reader ID-12LA (125 kHz) - Cooking Hacks
RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects. This is the ID-12LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing. Power the module, hold up a 125kHz card, and get a serial string...

Consider a Couple of Situations:
You are in a mall buying a lot of things and now you have to wait in the queue for a long time and when your time comes, the person at the counter checks each item for its barcode, scans it and then the computer processes it slowly. Overall it's a quite time consuming job both for you and the person at the counter.

RFID - Radio Frequency Identification
RFID, which stands for "Radio Frequency Identification," is a contactless identification technology that supports both low-frequency (125/134.2 kHz) and high-frequency (13.56 MHz) alternating magnetic fields. It consists of an information carrier (RFID tag, card or transponder) and a reading device (RFID reader or scanner). When the fields of one of those elements is within the reach range of the...

RFID tags are a type of tracking system that uses smart barcodes in order to identify items. RFID is short for "radio frequency identification," and as such, RFID tags utilize radio frequency technology. These radio waves transmit data from the tag to a reader, which then transmits the information to an RFID computer program. RFID tags are frequently used for merchandise,...
