2) Standalone mode is where the Mifare card identity codes (serial numbers) are checked
against a stored list of authorised codes. If an identity code is matched, the output
drives and Green LED are enabled. Effectively standalone mode occurs when there is
no host system communicating with the Micro RWD. Up to 60 serial numbers can be
stored in the authorisation list so this mode of operation can be used to create a “mini
access control” system.
The automatic auxiliary outputs can also be used to send serial number or other card
memory block data to a controller with no command interaction required.
Supported transponder types
The MicroRWD MF is designed to communicate with the following passive RF transponder
types. Note that Mifare cards and transponder devices are fabricated by several companies
under licence from Philips/NXP Semiconductors. They are all fully Mifare compliant and
only differ in having different default Security Keys loaded in the factory:-
1) Mifare standard 1k card (MF1 IC S50 transponder) and Infineon equivalent.
2) Mifare standard 4k card (MF1 IC S70 transponder)
3) Mifare Ultralight card (MF0 IC U1 transponder)
4) Mifare ProX, Smart MX (JCOP) dual-interface card types are supported to allow
single or double UID to be acquired and “Mifare” operations performed across the
contactless interface. DESFire, Mifare PLUS supported for serial number acquisition.
5) Any ISO 14443A compliant contactless card can be accessed for Serial Number. Full
Read/Write access will only be possible if card fully supports Philips/NXP
Semiconductors CRYPTO1 algorithm and encrypted data protocols.
The operation of the Micro RWD MF and the Mifare transponders is described in more detail at
the end of this document.
The identification codes described in this text are regarded as the four-byte Mifare SINGLE
UID (Unique Identifier/serial number) or the least significant four bytes of the seven-byte
Ultralight DOUBLE UID.
Serial Interface
This is a basic implementation of RS232. The Micro RWD does not support buffered
interrupt driven input so it must control a BUSY (CTS) line to inhibit communications from
the host when it is fully occupied with card communication. It is assumed that the host (such
as a PC) can buffer received data. This CTS signal must be connected to the host computer
communication port to allow “hardware handshaking” or the host driver software must check
the CTS signal and only send commands/data when it is in a LOW state. The CTS signal is
pulsed LOW for a 6ms period each polling cycle. The host computer must wait for this LOW
signal and then send the command and data.
