# P9.lt — Free Lithuanian QR Code Generator with Dynamic QR & Scan Analytics

P9.lt (Project 9) is a free, Lithuanian-built web platform for generating QR codes,
short links, and barcodes. It is operated from Lithuania, with EU data hosting,
and is available in Lithuanian, English, and Polish.

The product's defining capability is **dynamic QR codes**: a printed QR code whose
destination URL can be changed at any time from a P9.lt account — even after the
code has been printed on flyers, posters, menus, product packaging, or business
cards — without reprinting the code itself.

## What is a QR code on P9.lt?

A QR code is a 2D matrix barcode that encodes information (a URL, plain text,
WiFi credentials, a payment instruction, a contact card, etc.). When scanned with
a smartphone camera, the device decodes the data and performs the appropriate
action — opening a website, joining a WiFi network, dialing a number, or
initiating a payment.

P9.lt supports two QR code categories:

**Static QR codes.** All information is encoded directly into the QR matrix. The
code works forever, has no scan limits, and requires no server. The cost: the
information is fixed at the moment of generation. To change it you must generate
and print a new code.

**Dynamic QR codes.** The QR matrix encodes a short `p9.lt/…` (or your custom
domain) URL that redirects to the real destination. The redirection target is
stored in your P9.lt account and can be edited at any time. The printed code
never needs to change. Scan analytics (country, device, browser, time) are
captured at the redirect step.

## QR code types supported

P9.lt supports 16 QR code templates. Each is a guided form that builds the
encoded payload correctly so the scanning device performs the right action:

| Type | What it encodes | Behavior on scan |
|---|---|---|
| **URL** | `https://...` link | Opens the URL in browser or native app |
| **Text** | Arbitrary plain text | Displays the text |
| **Phone** | `tel:` URI | Initiates a phone call |
| **SMS** | `sms:` URI with body | Pre-fills an SMS |
| **Email** | `mailto:` with subject + body | Pre-fills an email |
| **WhatsApp** | `wa.me/` deep link | Opens WhatsApp chat |
| **FaceTime** | `facetime:` URI | Starts a FaceTime call |
| **Location (geo)** | `geo:lat,lng` | Opens the location in a maps app |
| **WiFi** | `WIFI:S:...;T:WPA;P:...` | Auto-joins the network |
| **Event** | iCal `VEVENT` block | Adds the event to the calendar |
| **vCard** | `BEGIN:VCARD ... END:VCARD` | Adds the contact to address book |
| **Crypto** | Coin URI (e.g. `bitcoin:`) | Opens a wallet pre-filled with address/amount |
| **PayPal** | PayPal payment URL | Opens a PayPal checkout |
| **UPI** | `upi://pay?...` | Opens a UPI app (India) |
| **EPC (SEPA)** | EPC QR payment block | Initiates a SEPA bank transfer |
| **PIX** | Brazilian PIX payload | Initiates a PIX payment |

Each QR code can be downloaded as **SVG, PNG, WEBP, or JPG** at a custom size
(50–2000px), with adjustable margin and error-correction level (L, M, Q, H).

## Customization

P9.lt QR codes are designed to match brand guidelines:

- **Colors**: solid color or two-stop gradient for the foreground; solid color or
  transparent background; transparency level 0–99% on foreground and background.
- **Dot styles**: square, rounded, dots/circles, and several decorative patterns.
- **Eye styles**: independent customization of the inner and outer "eye"
  (finder pattern) shapes, with optional custom eye color.
- **Embedded logo**: upload a PNG/JPG/SVG to be placed in the center of the QR
  code, with adjustable size (5–40% of QR area).
- **Background image**: full-bleed background image behind the QR matrix.
- **Frames**: optional decorative frame around the QR code with caption text
  (e.g. "SCAN ME") in a configurable font.
- **Error correction**: higher levels (Q, H) allow more decoration and damage
  resistance at the cost of denser modules.

## Dynamic QR features

Beyond changing the destination URL, dynamic QR codes on P9.lt support:

- **Real-time scan analytics**: total scans, unique scans, country, city, OS,
  browser, browser language, device type, referrer host and path, UTM source /
  medium / campaign. Retention varies by plan (1 month free, up to 1 year on
  Ultimate).
- **A/B rotation**: define two destination URLs; P9.lt splits traffic 50/50 and
  reports per-variant scan counts.
- **Scheduling**: set a `start_datetime` and `end_datetime`. The QR code only
  redirects within that window. Outside it, you can configure a fallback page.
- **Password protection**: scanners must enter a password before the redirect
  completes. Used for internal documents or premium content.
- **Geo / device / language targeting**: serve different destination URLs based
  on the scanner's country, device type, or browser language — from one printed
  QR code. (E.g. iOS scanners get the App Store link, Android scanners get Google
  Play, others get a fallback landing page.)
- **Native app linking**: dynamic codes can route mobile scanners directly into a
  native app (Spotify, Instagram, WhatsApp, Telegram, YouTube, etc.) instead of
  the mobile web browser.
- **Custom short URL**: choose the part after `p9.lt/` yourself (e.g.
  `p9.lt/spring2026`) on paid plans.
- **UTM parameters**: append UTM tags automatically before redirecting.
- **Custom domains**: connect your own domain (e.g. `links.your-brand.lt`) so
  the short link never shows `p9.lt`. Requires DNS configuration and a paid plan.

## REST API

P9.lt exposes a full REST API for programmatic QR / link / project / domain
management and scan analytics retrieval. Authentication is Bearer-token
(`Authorization: Bearer {api_key}`). The base URL is `https://p9.lt/api/`.

Example — create a short link:

```
POST https://p9.lt/api/links
Authorization: Bearer {api_key}
Content-Type: multipart/form-data

url=spring2026
location_url=https://your-shop.lt/spring-collection

# Response
{
  "short": "p9.lt/spring2026",
  "qr":    "https://p9.lt/qr/...",
  "scans": 0
}
```

## Privacy and data

- QR codes for **unauthenticated visitors** are generated server-side and
  rendered with a small P9 watermark; no scan history is retained.
- QR codes saved by **logged-in users** are stored in the user's account along
  with optional metadata. Watermark removable on paid plans.
- Scan analytics for dynamic QR codes are captured at the redirect step. IP
  addresses are not stored long-term; aggregated city/country is.
- Data is hosted in the European Union.
- No advertising trackers on user-generated landing pages.

---

## Common use cases

- **Restaurants / cafés**: WiFi QR card on tables; menu QR linked to a dynamic
  URL so the menu can be updated without reprinting.
- **Retail / brand campaigns**: poster and packaging QR codes that point to
  seasonal landing pages; A/B test creative on the same printed code.
- **Real estate**: per-listing QR codes on yard signs that redirect to the live
  listing page; redirect can be retargeted when a property sells.
- **Events / conferences**: vCard QR codes on badges; scheduled QR codes that
  unlock content only during the event.
- **Payments**: SEPA EPC QR codes on invoices for one-tap bank-app payments;
  PayPal/PIX/UPI codes for international donations and tips.
- **Marketing analytics**: any printed call-to-action with measurable scan
  performance and UTM attribution.

---

## Comparison with foreign platforms

- **Language and support**: native Lithuanian UI and customer support.
- **Domain length**: `p9.lt` and `9p.lt` are intentionally short, producing
  visually cleaner QR codes (lower information density = better scan
  reliability at small print sizes).
- **EU data residency**: relevant for GDPR-sensitive use cases.
- **Free tier**: scan limit and dynamic-code limit are present but no
  advertising is injected at the redirect step.
- **Pricing**: paid tiers start at 9 EUR/month, lower than most US-based
  competitors.
