QM30 Stationary Scanner

Stationary Scanner

An ultra-compact scanner for 1D and 2D codes. Its ideal applications include healthcare, pharma, and retail.

Key Benefits

Our Smallest Scanner

DENSO’s advanced technology reduces the lens size and provides trouble-free scanning in a module that is one-fourth the size of the QB30 and weighs a mere 18g (0.64oz).

Works in Other Devices

At only 3.5 cm wide, the compact QM30 makes scanning possible for devices previously denied the capability, such as ATMs and money exchanging machines, POS registers, ticketing machines, and coin counters.

Supports Security

The QM30 works with Secure QR Codes (SQRC) to support verification of authorized member ID cards and similar applications.

Smartphone Compatible

The QM30 scans codes displayed on smartphones for payment purposes. It also scans codes printed on paper.
