Frequently Asked Questions

Racket Tag started as a hobby project and lets you create QR codes for your rackets. Scan the code to see the string type, tension, and other details you recorded.

You fill in your setup once and reuse it at every shop, which means fewer forms and fewer translation errors. Racket Tag captures the specifics a paper form often misses — per-string-bed tensions, pre-stretch, knot types, notes — so stringers get it right the first time. Read the full story

Buy sticker paper (A4 or US Letter adhesive label sheets) from any office supply store. Download the QR image or A4 sheet from the Stickers page, then print it on your inkjet or laser printer. For best results use a laser printer — the prints are more durable and water-resistant. Apply the stickers to your racket's butt cap.

Download the QR image or A4 sheet and save it to your phone or a USB drive. Take it to a copy shop or office supply store with a printing service and ask them to print on sticker paper or vinyl sticker material. Vinyl stickers are ideal — they're waterproof and resist wear from handling.

Yes. From the Stickers page, select your cards and choose 'Order stickers' to get professionally printed kiss-cut stickers shipped to you. Each sheet contains 12 stickers sized for your sport (badminton, squash, or tennis).
