Use Matplotlib to create graphs.\r\n\r\nNeed more info about the check-in/check-out process. Is there some person with the laptop and scanner sitting there checking out devices? That is to say, maybe the user walks up, enters their information (or scans a badge, maybe?) and the person doing the checkout validates the information and scans the device and hands it to them and sends them on their way? That's one possible scenario. Is that the kind of thing you're envisioning?\r\n\r\nWhat condition would alert you to the fact that a device was not checked in or out properly?\r\n\r\nMy recommendation will be dependent on the answers to the questions above.","subreddit_name":"learnpython","author":"lanemik"},{"body":"[These](https://www.amazon.com/gp/product/B01GDJ2BH6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8\u0026amp;th=1) work pretty well for scanning and they're cheap.

How about you read your own link where it even says:\r\n\r\n\u0026gt;Laser - This type of illumination method uses a single point red laser diode similar to a laser pointer. The point of light is expanded into a line by oscillating the laser into a stationary mirror, or projecting the point into an oscillating mirror.  This illumination method is very popular because of the working distances typically achieved are superior to the point illumination or linear LED illumination methods. Typical working distances are from 1\" to 18\". By increasing the power of the laser and decreasing the angle of oscillation, ranges of over 20 feet can be obtained.\r\n\r\nOr here, watch this video by EEVblog where he disassembles a commonly used omnidirectional Laser Barcode Scanner:\r\n\r\nhttps://www.youtube.com/watch?v=PIn00-qW5WI\r\n\r\nOr [read this](https://www.barcodesinc.com/info/buying-guides/barcode-scanners.htm) where it says:\r\n\r\n\u0026gt;Laser - This is the most well known scanner type. It uses a red diode laser to read the reflectance of the black and white spaces in a barcode. Laser scanners are only able to read standard linear (1D) barcodes but are also the most cost effective option. Standard laser scanners can read from a few inches to a foot or two away depending on the size of the barcode. There are also extended range laser scanners, like the Zebra LS2208, which can read up to 35ft away when using large reflective labels.\r\n\r\nOr check out [this handheld barcode scanner which even has the laser symbol on the front](https://www.amazon.com/NADAMOO-Transmission-Automatic-Supermarket-Warehouse/dp/B01GDJ2BH6/ref=pd_lpo_vtph_229_bs_t_1?_encoding=UTF8\u0026amp;psc=1\u0026amp;refRID=HZHA3N2C6G3KHBNV9B8J)\r\n\r\nAnd [here you got an explanation why lasers are different from focused light](http://wtamu.edu/~cbaird/sq/2014/04/17/how-do-you-focus-regular-light-to-make-it-a-laser-beam/)\r\n\r\nSo please, CCD or array based scanners are a rather new development and I even asked you if you are talking about Linear Imagers which you completely ignored and staretd to ramble how low powered lasers are just focused light. The classical barcode scanners used for decades use lasers which are different from focused light.\r\n\r\n","subreddit_name":"funny","author":"FalconX88"}]}
