Creating Codes

You can create a new code in two ways:

By content type — fill in structured fields (for example URL, contact, or Wi‑Fi). The app builds a valid QR payload for you.
By code type — choose a format (QR or a supported linear barcode) and enter the raw value yourself.

Supported Scan Content

Qrexium can recognize and process many kinds of information encoded in QR codes and barcodes, including:

Website URLs
Plain text
Contact cards (vCard)
Calendar events (iCalendar)
Phone numbers
Email addresses
SMS messages
Wi‑Fi network configuration
Geographic coordinates and map locations
Payment-related QR and payment-URI formats

Depending on the scanned content, Qrexium may offer quick actions such as opening a website, saving a contact, adding a calendar event, or connecting to a network.

Supported Payment Types

Qrexium recognizes the following payment-related formats:

UPI — India: upi://pay and similar UPI QR payloads
SEPA / GiroCode (EPC) — Europe: credit-transfer QR (BCD + IBAN, recipient, amount, references)
PIX — Brazil: EMV payloads with PIX / static key heuristics
Swish — Sweden: swish:// payment requests

Common Questions

What code types are supported?

Qrexium supports generating and scanning the following symbologies (exact camera support can vary by device and platform):

2D — QR Code, Micro QR, Aztec, Data Matrix, PDF417, Micro PDF417
Linear — Codabar, Code 39, Code 93, Code 128, EAN-8, EAN-13, ITF (Interleaved 2 of 5), UPC-A, UPC-E

Scanning a code from a photo may recognize additional barcodes in some cases; the app stores and displays the decoded content in a consistent way across Android and iOS.

How can I add a code?
You can add a code in three ways: create it manually, scan it from an image, or scan it using your device camera.

Where is my data stored?
Generated and scanned codes are securely stored in your account using cloud storage (Firebase Firestore) and are accessible only after login. Data is transmitted and stored using industry-standard security measures.

Account & data deletion
To request account deletion or data removal, either email support at qrexium@gmail.com or submit the request through the app.
