While not standard, some fingerprint scanners incorporate an LED light to help you use it in low-light conditions. The best and most versatile option is to go with a fingerprint scanner that includes both a short and a long cable. For desktop computers, a longer cable may be necessary. Shorter cables are better for use with a laptop, where you don’t need a lot of cable to easily access the scanner and extra cable would only be in the way. If a fingerprint scanner uses a cable, be sure you know the length of the cable, because some are short and some are long.
