Description: This RFID reader-USB made by rhydoLABZ, reads EM4100 family transponder tags that are brought in proximity to the reader and output the unique tag identification number through serial port @9600 bps. It is working at 125Khz is suitable for most widely used RFID Cards some times called as Proximity card also.The normal detection range is 10-15CM for Card Type TAGs.The power for the reader is taken from the USB port, which is protected by 500ma SMD Fuse.

The reader output 12 byte including one start, stop byte and 10 unique data byte.The start byte and stop byte are used to easily identify that a correct string has been received from the reader (they correspond to a line feed and carriage return characters, respectively). The middle ten bytes are the actual tag's unique ID. Vertical and horizontal parity checking has been done in card reading algorithm to ensure data integrity.One status LED is provided to indicate card detection.

This RFID Reader  uses the EM4102 protocol , tags that use the EM4102 protocol can be used with the rhydoLABZ RFID reader.All communication is 8 data bits, no parity, 1 stop bit, non-inverted, least significant bit first (8N1). The baud rate is configured for 9600bps, a standard communications speed supported by most any microprocessor or PC, and cannot be changed. The rhydoLABZ RFID Reader Module initiates all communication.

RFID (radio frequency identification) systems use data strings stored inside RFID tags or transponders) to uniquely identify people or objects when they are scanned by an RFID reader. These types of systems are found in many applications such as passport protection, animal identification, inventory control systems, and secure access control systems,robotics, navigation, inventory tracking, payment systems, and car immobilization. Because passive tags require a strong RF field to operate, their effective range is limited to an area in close proximity to the RFID reader. The distance over which the RFID tag is usable is affected by such things as the tag shape and size, materials being used in the area near the reader, and the orientation of the reader and tag in respect to each other and in their operating environment. The smaller a tag, the closer it must be to the reader to operate.  Each transponder tag contains a unique identifier (one of  1,099,511,627,776, possible combinations) that is read by the RFID Reader Module and transmitted to the host via a simple serial interface.

There are a variety of transponder tags that come in different packages. Each tag has a specific range that is within 10% of the given distance for each type of tag. The reason for the 10% is due to environmental conditions and RFID modules.

I had no experience with these kind of embedded devices. A pure software engg by profsn, it was the first time that I had to deal with electronics. Had to work with these RFID readers, which was to be used in connection to an Android platform creating logs! I was scared being a newbie.. but it was easy! these guys guys here made it possible. Rhydolabz has high quality products and a real good tech support!
