SECTION 1. OVERVIEW
The MICRSafe with 3-Track MSR is both a MICR (Magnetic Ink Character Recognition) Check
Reader and an MSR (Magnetic Stripe Reader).
The MICRSafe, in a typical application, reads the magnetic data encoded on the bottom of
checks or on magnetic stripe cards and transmits this data to a Host device. The Host device then
uses a specific authorization or verification process to validate a business transaction.
The use of the MICRSafe improves accuracy and speed because there is no manual data entry;
therefore there are no keying errors or unwanted delays.
The MICRSafe has three interface capabilities. First, the MICRSafe can communicate with the
Host system using a standard USB interface. The driver will emulate a serial port on the host
PC. All data is transmitted as ASCII characters (See Appendix D). This is MICRSafe VCOM
unit.
Second, the MICRSafe can emulate a USB keyboard. This device is compatible with PCs or
hosts that support USB keyboards. The Reader emulates a USB Human Interface Device (HID)
United States keyboard or optionally all international keyboards using ALT ASCII code keypad
key combinations or customizable key maps. This allows host applications designed to acquire
card data from keyboard input to seamlessly acquire the card data from the reader. This is
MICRSafe HID unit.
Caution
If another keyboard is connected to the same host as this device and a
key is pressed on the other keyboard while this device is transmitting,
then the data transmitted by this device may get corrupted.
Because of potential “data interleave” issues associated with the USB Keyboard interface,
MagTek recommends that this product should only be used if the application requires data to be
provided via the keyboard input.
Third, the MICRSafe can communicate with a device other than the host, for instance a POS
terminal, through an auxiliary RS-232 interface. All data is transmitted as ASCII characters (See
Appendix D). The MICRSafe has the capability of supporting some hardware handshaking
signals. (See Section 4, Legacy Commands.) Depending on POS connection port, a ‘Mini DIN 9
Pin’ or a ‘DB9’ cable can be used to connect. Communication in this mode is one-way only,
outputting data from the MICRSafe to POS terminal. Baudrate is always set to 9600 bps.
