iOS, is the operating system used on Apple iPhone, and iPad. Opticon manufactures and sells a variety of Bluetooth capable barcode scanners that can be used with iOS. iOS is capable of interfacing with Opticon barcode scanners using Bluetooth HID. Not all Opticon bluetooth capable barcode scanners are capable of the Bluetooth HID interface, however most of the bluetooth barcode scanners we currently sell (not legacy products) are capable of bluetooth HID. Most notably among the Bluetooth HID capable are the [OPN2002], [OPR3301], and the [OPI3301]. The OPN2002 is by far the most popular to use with the iPhone and iPad because of its small form factor and its ability to toggle the iOS virtual keyboard using the function key.
