HID® iCLASS® RWK400 Reader/Writer Keypad Reader

HID® iCLASS® RWK400 Reader/Writer Keypad Reader


Using 13.56 MHz contactless smart card technology, the iCLASS® RWK400 provides a powerful solution. Combine a contactless card presentation with a personal identification number (PIN) to support dual authentication of identity. Or, configure the panel for single-factor authentication, using only a card or a PIN.

The PIN can be verified either at the access control panel or locally by the keypad reader. When verified locally, the PIN must be programmed into the iCLASS card.

The RWK400 offers the same features as the RK40, with the extended ability to read/write user data to HID iCLASS credentials. Read/write applications include the storage/retrieval of data such as biometric templates, health records, time and attendance, and digital cash. The possibilities are endless!
