Micro QR
A QR code shrunk for places a full QR will not go.

- Built for
- Very small marking areas
- Standard
- ISO/IEC 18004
A standard QR Code spends three of its corners on finder patterns — the big concentric squares a scanner uses to locate and orient the symbol. On a code a few millimetres across, that overhead is most of the available space. Micro QR keeps one finder pattern instead of three, which is what lets it shrink.
The trade is capacity. Micro QR holds far less than a full QR, so it is used where the thing being identified needs a short code rather than a URL — a serial number, a part reference, a board identifier.
You meet it on electronics and components: a pad on a circuit board, the flank of a connector, a small medical or laboratory item. Anywhere the engineer had a few square millimetres and still needed the part to be machine-readable.
Where you meet it
A QR too small to be a QR: a pad on a circuit board, the flank of a component.
Can a phone scan a Micro QR code?
A normal QR scanner app will usually not, because Micro QR is a separate symbology rather than a small QR Code — the single finder pattern means a standard QR decoder does not recognise it. With TRAKWIND Scan selected, the keyboard reads it and types the value into whatever field you are in.
How to scan it with your phone
- 1
Install Barcode & QR Scanner Keyboard from Google Play and enable it as a keyboard.
- 2
Open Settings → Scanning engine and choose TRAKWIND Scan.
- 3
Tap the barcode key on the keyboard and point the camera at the code.
The value is typed into whatever field you were already in — a spreadsheet, an ERP screen, a web form. There is nothing to integrate.
