How Translation Pens Work
The basic process is: printed word, scan, OCR, translation. Depending on the product, translation may happen on the device, through connected software, through a mobile application, online, or offline.
What to Check Before Buying
Don't judge a translation pen solely by the number of advertised languages. Check source languages, target languages, offline languages, online languages, dictionary support, sentence translation, pronunciation, and OCR support.
Translation Pen vs. Translation App
A smartphone app is usually more flexible. A dedicated translation pen can be faster for single words or short printed passages because the scanning function is built into the device.
