They often have the same or similar Imagers that the Android OS Touch Computers have. In the keyboard emulation mode, they can scan barcode data into the native and web form fields of connected iOS and Android OS smartphones and tablets.
Pros: Generally, they offer the same benefits as Android OS Touch Computers. However, the scanning speed and accuracy can be quite poor with inexpensive models. Therefore, it’s best to avoid low-end devices unless they have positive reviews. The cost is moderate, even for the better models. However, you need to also consider the cost of the data receiving devices, such as smartphones or tablets.
Cons: Likewise, they have the same issues as Android OS touch computers. Typically, the biggest issue is that they can be awkward to use in the field since the app-user must handle two devices. More specifically, users must handle the accessory and the connected device. Nevertheless, the connected device can use the latest smartphone technology.
