About Q4

QR codes should be the easy part. But we kept seeing the same thing happen: a restaurant switched menu software, a business moved its booking system, a website was rebuilt, and the new links were just slightly different. Every printed menu, table card, poster and label now pointed nowhere. The usual fix was to make new codes and pay to reprint everything.

The problem is that most codes point straight at someone else's software. Q4 sits in between. Your printed code points at Q4, and Q4 points wherever you need it: this year's menu platform, next year's booking system, this month's campaign. Change suppliers whenever you like, and your codes stay exactly as they are, for as long as you need them.

Who we are

Q4 is made by Apperrific, an Irish application software company with over 20 years of experience building and running software that businesses depend on.

Privacy and security at the heart of what we do

Modern security and privacy practices are at the forefront of everything we build: from GDPR compliance, to appropriate use of encryption, to web application technologies that safeguard your data at all times. We count scans, not people: scanning a code sets no cookies and builds no profiles of the people who scan.
