QR codes for San Francisco businesses and events

A QR code for a San Francisco business links a printed sign, badge or market stall to a page on a phone: a sign-up form, a menu, a product page or a tour booking. linqr codes are dynamic, so you can change the destination after the code is printed and keep using the same banners, stickers and table cards.

What makes a QR code useful in San Francisco

In San Francisco a QR code is useful when it saves someone a step, because the audience is used to scanning and quick to skip anything that wastes their time. People here scan codes at meetups, markets and cafes without a second thought. What they will not do is type a long URL or wait for a slow page.

linqr gives you a short link, onsonara.com/q/…, behind every code, and you can change its target in your account at any time. linqr is an online tool, not a Bay Area agency, and it works the same everywhere. You start with the free QR code generator; the ideas below are about using it well in the city. For more places, see the city guides.

Tech conferences, meetups and demo days

At a tech event the best code opens exactly one thing: the demo, the waitlist, the repo or the job post. Moscone Center hosts large tech conferences, and the city has a constant flow of smaller meetups, hackathons and demo days in offices and coworking spaces. Attendees scan dozens of codes in a day, so yours should be clear about what they get.

  • Booth and sticker codes: point to a waitlist or a trial page with a frame that says what happens, like “JOIN THE BETA”.
  • Last slide of a talk: a code for slides and resources. Swap the link to the recording once it is published.
  • Swag and laptop stickers: a code for your careers page or community channel; update it when roles change.
  • Name badges at meetups: a code for each organizer's profile or calendar booking page.

Use a separate code for each event. With linqr's scan stats you can compare how many people scanned at a large conference versus a small meetup, and the Free plan covers 3 active codes to start.

Farmers markets, cafes and neighborhood shops

For market vendors and small food businesses a QR code replaces the questions they answer all day: where else can I buy this, do you deliver, what is in it. The Ferry Plaza Farmers Market and neighborhood markets across the city bring vendors face to face with customers who often want to buy again later.

  • Market stall sign: a code for your online shop or subscription box, so customers can reorder between markets.
  • Product labels: a code for ingredients, sourcing or recipes. Update the page when the harvest changes.
  • Cafes and bakeries: a code on the counter for the menu or preorder page; details in QR code for restaurant menus.
  • Boutiques in Hayes Valley, the Mission or North Beach: a window code for store hours and the online shop, useful when the door is closed.

Ask the market organizer about their sign rules before you print a banner; each market sets its own.

Tourism: cable cars, the waterfront and visitor guides

For businesses that serve visitors, a QR code is the quickest way to hand over a map, a booking page or a guide in several languages. Tourists spend their days around Fisherman's Wharf, Union Square, Chinatown and the cable car lines, often with a phone in hand and no idea where to eat next.

  • Tour operators: a code on the ticket stand for departure times and booking. Change it when the schedule changes for fog or wind.
  • Hotels and hostels: a code in the lobby or on the key card sleeve for your own city guide and transit tips.
  • Bike rentals for the Golden Gate Bridge ride: a code for the route map and a waiver form.
  • Restaurants near the waterfront: a code for the menu with prices, since visitors like to check before they sit down.

If you plan to post a sign on a pier, sidewalk or public plaza, check with the property owner, the port or the city first. linqr only makes the code.

Create a San Francisco code step by step

  1. Copy one clear destination

    A waitlist, shop page, menu or booking form. Open it in a private window to be sure it loads without a login.

  2. Paste it into the creator at the top

    The “mint-lines” style and a “SCAN TO JOIN” frame are preset. Replace the label with your call to action, such as “SHOP ONLINE” or “BOOK A TOUR”.

  3. Style the code

    Upload a logo, pick colors with enough contrast and wait until the creator shows Scans correctly.

  4. Download, save and test

    Click Download QR code and save the code to a free account. Print a test copy and scan it where people will stand, in fog as well as sun if it goes outdoors.

Fog, hills and wind: print tips for the city

San Francisco weather is mild but damp: fog, drizzle and wind wear out paper signs faster than you think. Outdoor codes should go on weatherproof vinyl or rigid board and be fixed firmly, because a flapping banner is hard to scan. The QR code printing guide explains which file to send and how to size it.

Market stall sign3-5 ft4-6 in
Booth backdrop6-10 ft8-12 in
Cafe counter card12-20 in1.5-2 in

On a steep street people stand at an angle to your window, so place codes low enough to face them directly and avoid reflective glass where the afternoon light hits.

Reviews and measuring results

Once customers have scanned your menu or shop page, a review code can bring them back to your listing. A “REVIEW US” card by the register can open your Google review form; the details are in QR code for Google reviews. Every linqr code also records scans: totals, unique scans, a 30-day chart, top countries and devices on Free, and cities, hours and a year of history on Pro.

Questions

Can I reuse one QR code across several San Francisco tech conferences?

Yes. Print the code on your booth graphics once, then change its link before each event, for example from a conference-specific landing page to your next demo day. In linqr you do this under My codes with Change link, and it takes effect immediately.

Is linqr a San Francisco startup?

No. linqr is an online QR code generator run by a company based in Katowice, Poland. It works in any browser, so San Francisco businesses and event organizers can create, edit and track codes without a local vendor.

What should a San Francisco farmers market vendor link a QR code to?

Link to whatever helps customers buy again: your online shop, a subscription or delivery sign-up, or your Instagram profile with market dates. Use one code per goal. If you add a new shop page later, change the link and keep the same stall sign.

How big should a QR code be on a San Francisco market stall sign?

For shoppers scanning from 3-5 feet away, a code 4-6 inches wide works well. Leave a clean margin around it, choose dark modules on a light background and use a weatherproof sign, since morning fog and drizzle can wear out paper quickly.

Can San Francisco tour operators change QR code schedules when the weather changes?

Yes. Point the code on your ticket stand to a schedule page and update that page, or change the link itself to a notice page on days when tours are delayed. With linqr, link changes are unlimited on every plan, including Free.

Can a San Francisco hotel give guests a QR code city guide?

Yes. Put your guide on a web page or PDF and link a code on key card sleeves or lobby signs to it. linqr does not host the guide itself, but you can update the page or change the link any time without reprinting the cards.

Do QR codes on San Francisco laptop stickers need to be large?

No. Stickers are scanned from about 8-12 inches away, so a code around 1 inch wide is usually enough. Keep the design simple, with strong contrast and a clean margin, and test the printed sticker before ordering a big batch for a conference.

Can I see where scans of my San Francisco event code come from?

Yes. On the Free plan linqr shows total and unique scans, a 30-day chart, top 3 countries and devices. Pro adds cities, systems, browsers, languages, a day-by-hour heatmap and CSV export, which helps compare visitors from the Bay Area with those from further away.

Are QR code signs allowed on San Francisco piers and sidewalks?

It depends on the location and who manages it. Rules for signs on piers, plazas and sidewalks come from the property owner, the port or the city, so ask them before you install anything. linqr creates the code and cannot confirm local permissions.

What happens to my San Francisco QR code if I stop paying for Pro?

Check the terms of service, linked in the footer: they set out what happens to codes after Pro ends. linqr codes have no expiry date, and the Free plan, with no trial or card, lets you edit 3 active codes with unlimited scans.
