The toolkit
All scanner tools
Eight tools, one decoder. Each opens with the scanner in the first viewport.
QR scanner
Open the camera, frame the code, read the content. The decoder runs locally on your device; images are never uploaded and history stays with you.

Barcode scanner
EAN-13 on a cereal box, Code 128 on a shipping label, Data Matrix in logistics: one decoder for linear and 2D codes, with a real check-digit analysis.
EAN-13 · EAN-8 · UPC-A · UPC-E
Image / screenshot
The code is not in front of your camera but inside a screenshot, a photo or a PDF? Drop the file here — decoding happens in your browser, not on a server.

EAN / UPC Scanner
Scan a product code, verify the check digit, place the registration prefix. The scanner tells you whether a GTIN can be genuine at all.

GS1 DataMatrix
Industrial codes carry more than a number: batch, expiry, serial, quantity. The scanner breaks the GS1 payload down into application identifiers.

Wi-Fi access
A Wi-Fi code contains the SSID, encryption type and password in the WIFI: format. The scanner separates the fields — useful when the label is gone.
WIFI: · WPA/WPA2/WPA3 · hidden SSID
Contact card
Digital business cards live inside QR codes. The scanner extracts name, organisation, phone, email and website into copyable fields.

Safety check
QR codes are invisible links. The scanner shows the destination before you click — and flags the patterns quishing relies on.

The network logic
Scanning is one half. The other is creation: QR codes for Wi-Fi, vCard, SEPA and links live on qrcodeerstellung.de, barcode symbologies on barcode.qrcodeerstellung.de, and print-ready logistics labels with VDA 4902, KLT and MAT on label.qrcodeerstellung.de.
All three share one rule: the tool comes before the explanation. This page links straight to the tools, never to marketing pages.
