Free QR codes that don't expire
A static QR code never expires, because the link is written inside the code itself. Codes that go through a service work only while that service keeps them running.
Make a static QR codeWhich QR codes never expire
A static code holds its content in the pattern itself: a link, a WhatsApp chat, a location or Wi-Fi details. Scanning it needs no server and no account, so it keeps working as long as the content itself is valid. On Albarcode, static codes are free with no sign-up.
Which QR codes can stop working
Some codes hold a short link that goes through a service: uploaded files (images, videos and PDFs) and smart or dynamic links, on any site. They work while that service keeps them running. On Albarcode they work while your subscription is active, stop if it ends, and work again when you subscribe.
Why a free QR code stopped working
Some generators make a dynamic code that stops working after a trial. To check a code, scan it with the QR code scanner and look at the link that appears. If it starts with the generator's own short domain, the code depends on that service.
Static or smart: which to choose
Choose static if the link never changes. Choose smart if you need to change where the code leads after printing or see how many scans it gets. Smart links are part of a monthly plan.
