Frequently asked questions
Quick answers about our products, integration and ordering. For anything else, our engineers are one message away.
01What is the difference between a scan engine, a scan module and a barcode scanner?
A scan engine is the bare optical and decoding core, designed to be built into your own device such as a PDA or medical instrument. A scan module is an engine in a housing with standard connectors, ready to mount in a kiosk, turnstile or counter. A barcode scanner is a finished handheld or desktop product that an operator uses directly.
02Which barcode types can Dokivision products read?
All current models read the common 1D symbologies (EAN/UPC, Code 128, Code 39, Interleaved 2 of 5 and others) and 2D symbologies such as QR Code, Data Matrix, PDF417 and Aztec. The full list for each model is in the Performance table on its product page and in the datasheet.
03Can the scanners read codes from phone screens?
Yes. Our modules for payment, ticketing and access control are tuned for on-screen codes, including dimmed displays and screens behind protective film.
04Which interfaces are available?
Depending on the model: UART TTL, USB HID keyboard, USB virtual COM, RS232 and RS485. Interfaces and connectors can be customized for OEM projects.
05Do you provide an SDK and integration support?
Yes. We provide configuration tools, command sets, SDKs and reference documents, and our application engineers support your team during integration and testing.
06Can you customize a product for our device?
Yes. OEM/ODM work is a core part of our business. Typical customizations include firmware behaviour, data formatting, cable and connector, mounting, housing colour and branding. Contact us with your requirements for an assessment.
07Can I get samples for evaluation?
Evaluation samples are available for most models. Send an inquiry with the model, quantity and your application, and our sales team will reply with availability and lead time.
