What should your WIA Code carry?

A WIA Code holds the content itself — not a redirect. Pick the kind of content below; every page explains the standard format, what a phone does when it scans it, how much fits, and shows a real example you can scan right now.

Everyday · sharing

A link, inside the codePut a web address in a WIA Code. Unlike a shortener, nothing sits in between: the scanner reads the address straight out of the code and shows it before opening it.Text that lives in the codeA note, an instruction, a message on a gift — stored in the code and shown as is when scanned. No link to follow, nothing to load.Wi-Fi, joined by scanningThe network name and password go into the code in the standard WIFI: format. Guests scan and join — nobody reads a 20-character password off a sticker.A place, in the codeLatitude and longitude in the standard geo: format, with an optional label. Scan and the phone opens its map at that exact point — a shop entrance, a meeting spot, a trailhead.An event that adds itselfTitle, start, end, place and a note in the standard iCalendar format. Scanning offers "add to calendar" — no ticket link, no sign-up page.A task, handed over by scanningA task with an optional due date and note in the standard VTODO format. Stick it on a kit, a machine or a door: whoever scans gets the task in their app.

Contact · messaging

A business card the phone can saveName, company, phone, email — inside the code as a standard vCard. Scanning offers "add contact". No card service in between, and it keeps working after the print run.Scan to callA tel: link in the code. The scanner shows the number and offers to call — for a service desk sticker, a delivery note, a lost-and-found tag.A text message, pre-writtenThe number and the message body go into the code. Scanning opens the messaging app with both filled in — the person only presses send.An email, ready to sendRecipient, subject and body in a mailto: link. Scanning opens the mail app with all three filled in — a feedback address on a receipt, a job application on a poster.

Payment · authentication

A note only the passphrase opensThe text is encrypted in your browser before it becomes a code. Whoever scans sees a locked card and needs the passphrase — a safe-deposit note, a recovery hint, a message for one person.A payment request the wallet understandsAddress, amount and label in the standard bitcoin: or ethereum: URI. The wallet fills in the payment; the person confirms. Works on a counter card, an invoice, a donation poster.

WIA Code is a radial-symmetry 2D code. The content lives in the code; there is no server in between when it is scanned. Generated with the WIA Code engine · scannable · no account needed
