I made this library inspired by \r\n[pyfingerprint](https://github.com/bastianraschke/pyfingerprint), so it may also work with ZFM-60, ZFM-70, ZFM-100,\r\nR303 and R305.\r\n\r\n## Terminology\r\n\r\n**Image**\r\n\r\n  Image is a Fingerprint scanned grayscale image. Image can be scanned and stored in volatile image buffer.\r\n\r\n**Characteristic**\r\n\r\n  Characteristic is a fingerprint characteristic. It represented by a bytearray. Characteristic can be created from \r\n  fingerprint image and stored in volatile characteristic buffer.\r\n\r\n**Template**\r\n\r\n  Template is a registered fingerprint model stored in scanner nonvolatile memory. \r\n  We can not see or feel the template, we only can ask scanner if characteristic look like some template \r\n  in scanner memory.\r\n\r\n## Working with sensor\r\n\r\n### Handshake\r\n\r\nFirst of all you need make a handshake to verify connection:\r\n ```python\r\nwith SerialPort(Serial(port='<COM1 or /dev/ttyUSB0>', baudrate=9600 * 6, timeout=2)) as port:\r\n    rq = RqCommand(port)\r\n    rs = RsSimple(port)\r\n    Handshake(rq, rs).make()\r\n```\r\nAs you see you will need to know serial port name of your scanner device. For windows users it may looks like `COM1`,\r\nfor unix users it may looks like `/dev/ttyUSB0`.\r\n\r\n### Fingerprint image\r\n\r\nMore complex task - make an image of your fingerprint:\r\n```python\r\nwith SerialPort(Serial(port='...', baudrate=9600 * 6, timeout=2)) as port:\r\n    rq = RqCommand(port)\r\n    rs = RsSimple(port)\r\n    print 'Waiting for finger...'\r\n    while not Scan(rq, rs).is_scanned():\r\n        pass\r\n    print 'Finger has been scanned! Downloading the finger image...'\r\n    image = UpImage(rq, rs).image()\r\n    image.show()\r\n```\r\n\r\n",
