IRIS Portable USB Scanner
IRIScan Express 4 — Portable USB Document Scanner
A slim USB scanner that needs no batteries and no warm-up: slide a page in, and it comes out scanned a few seconds later. The IRIScan Express 4 feeds one sheet at a time at up to 8 pages a minute at 300 dpi, in colour or black and white, and is powered entirely over its USB cable. A personalisable smart button sends a scan straight to the program of your choice, and the bundled Readiris OCR and Cardiris business-card software convert what you scan into editable text, PDFs or digital contacts.
Quick Glance
Key Features
USB powered, no batteries or warm-up
Connect it by USB and it is ready — there is no battery to charge and no warm-up time. The USB socket sits on the side, so the cable stays out of the way while a page feeds through.
One-click scanning with Smart Readiris
A personalisable smart button sends a scan straight to the program of your choice. Smart Readiris OCR software then converts scanned pages into editable Word files, indexed PDFs, audio files or ePub, and recognises more than 138 languages.
Doubles as a business-card scanner
Cardiris business-card software reads the contact details on a scanned card and exports them to Outlook, Excel, Salesforce or similar, alongside everyday document and receipt scanning.

Need-to-Know
The Express 4 is IRIS's simplex single-sheet scanner; the Executive 4 adds duplex, and the Anywhere 6 WiFi models add wireless scanning at a faster rated speed.
- This is a single-sheet scanner, not an automatic document feeder — pages are slid in and scanned one at a time, so it is not built for large unattended batches.
- There is no Mac driver listed for this model; IRIS states Windows 7, 8, 10 and 11 only, and setup needs an internet connection to download the software.
- It is USB powered with no battery, so it needs a computer's USB port to run — it will not scan standalone.
- For double-sided pages in one pass, the IRIScan Executive 4 in this range adds duplex scanning; the Express 4 scans one side per pass.
