The rhydoLABZ RFID reader 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. 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. The normal detection range is 10-15CM for Card Type TAGs.The RFID Reader (as well as the RFID tags sold by rhydoLABZ) uses the EM4102 protocol. Any other tags that also 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. The rhydoLABZ RFID Reader Module can connect directly to any TTL-compatible UART or to an RS232-compatible interface by using an external level shifter.
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.

Very nice and easy to use product. Very small layout so can fit easily in enclosure. I was searching for something like this.

Hi Brijesh,

As per the driver specification, UNO can only drain a maximum of 100mA. On the other hand, UNO & RFID reader together consumes about 130mA as a whole. From this you can understand that insufficient current is the reason why the module power goes off when connected together and powered via USB. For this particular application, using a power supply adapter(for powering) along with the USB(for comm.) will be a great choice.

    • Q
    • i need to know the working range of this device.

      asked by MIDHUN PRASAD on November 08, 2016
    • A
    • As per the datasheet the reading distance is 10-15cm of the reader depends on the card shape.

    • Q
    • Does it reads all kind of tags?

    • The RFID Reader uses the EM4102 protocol. Any other tags that also use the EM4102 protocol can be used with the RFID reader.
