A QR on your packaging turns "I opened the box" into "I watched the setup video". qr.paps.jp generates it for free; the rules below cover sizing, placement, and how to keep the destination updatable long after the package ships.
In consumer electronics and DIY, 30-40% of support calls are "I didn't read the manual". A QR to a 60-second setup video delivers in a form customers actually consume — some brands cut support contact rates by half.
qr.paps.jp lets you change the destination of the short URL after shipping. Add a FAQ page, link to a recall notice, swap to a new tutorial — the box keeps working.
Point the QR at the Amazon product review page or your Google Business Profile. Reviews placed at the moment of first-use (not weeks later) land at 2-3× the normal rate.
Setup video, support page, review page, or user registration — one or two destinations max per QR.
Long YouTube URLs especially benefit. A custom slug like qr.paps.jp/product-manual stays memorable.
1.5-2.5 cm sq. Back or base. Instruction line ("Scan for the setup video").
utm_source=amazon vs utm_source=rakuten lets you see which channel buyers scan more. qr.paps.jp auto-appends.
Lighting matters. Test under store fluorescent and home soft-white. Any press misregistration kills scans.
