6.1.3 Mutual Authentication
Mutual authentication* is the process of two units authenticating each other. Between a controller and Reader/Writer, this
is performed by using the following elements in order to provide protection against fraudulent access, tampering, spoofing
and other illicit data manipulation.
1. Two 56-bit keys
2. ISO9798-2 compliant authentication model comprising three paths
3. Encryption algorithm
* For more information about mutual authentication and encryption, refer to the “Reader/Writer Command Reference
Manual”.

7. Security
Illicit data access and tampering that may occur during communication are serious security risks to any IC card system.
To safeguard against such risks, the Reader/Writer encrypts and decrypts data transmitted to and received from the card,
whereas the same is performed by the controller for security protection of data communication between the controller and
the Reader/Writer. More specifically, the following must be observed to ensure secure system operation.
1) Communication between the controller and the Reader/Writer must always be performed in the encryption mode. Data
flows through the communication path when the Reader/Writer communicates with the card in accordance with the
command received from the controller. The path must therefore be protected by turning on the encryption mode and
performing mutual authentication between the controller and the Reader/Writer.
2) Access keys used for mutual authentication between the controller and the Reader/Writer must be updated periodically.
Leakage of key information can result in surreptitious use or divulgation of eavesdropped data, and in the worst case,
may seriously affect the operation of the entire system. Do not continue to use factory-preset access keys (Kar, Kbr)
without changing their values, especially for mutual authentication in actual applications.
The access keys can be changed by using the Change Reader/Writer Access Key command.
For more details, refer to the “Reader/Writer Command Reference Manual”.

9. Precautions
9.1 Precautions for Installation
The RC-S493B Reader/Writer must be installed with special care as described below. For optimal installation, also refer to
the “RC-S460/490 Series Reader/Writers Installation Requirements and Evaluation Methods”.
9.1.1 Reader/Writer
• Maximum communication distance can be ensured only when an RF/control board is used in combination with an antenna
bearing the same serial number. With other combinations, there is no guarantee of the communication distance.
• Remove any source of electromagnetic noise from the antenna coverage area. The same can be said of any object that
may reflect or interfere with electromagnetic waves. In a system accommodating multiple Reader/Writers, antennas must
be separated from each other for a distance of more than 30 cm in order to ensure the max. communication distance of
30 mm (when used with the RC-S860 Series/RC-S880 Series/RC-S833) or 20 mm (when used with the RC-S890). Note,
however, data communication remains possible even when the distance between two antennas is less than 30 cm, although
the communication distance is shortened.
• Connecting the Reader/Writer’s GND terminal to the ground line of its enclosure is not recommended.
• Communication performance may be affected by power line noise and the harmonics of the 13.56 MHz carrier signal.
• Communication performance may also be affected by the high-frequency noise (800 MHz or higher) generated by mobile
phones.
• Transmission/reception performance of communication devices such as mobile phones may be affected when they are
brought very close to the Reader/Writer.

9.2 Handling Precautions
The RC-S493B is module products designed for built-in use. It must be handled carefully, keeping the following precautions
in mind.
• Be careful when handling the board edge and case edge and lead connector so that you do not hurt your hands.
• Do not throw the module to a person.
• In order to prevent short-circuiting, do not soil the exposed part of the terminal with metallic substances such as solder
residue.
• When plugging and unplugging the connector cable, make sure that it is inserted correctly without any wire disconnection.
If connected inversely, the Reader/Writer may ignite or emit smoke.
• Handle the module with care as it contains delicate electronic circuits.
• Do not shut down or reset the Reader/Writer while data is being written into the internal non-volatile memory (EEPROM).
In this case, the Reader/Writer cannot be re-started.
