A cheap thermal printer for kids is around 10-20 USD (got one for such price with 10 rolls of paper, half of which is sticky paper), has bluetooth, usb and battery. Fits in a pocket. Would be fun to stick such qr code inside some not important book left lying around.
- Sabinus 3y agoI would caution about giving children receipt paper. It may contain a lot of BPA (or replacements). https://www.smh.com.au/business/consumer-affairs/controversial-chemical-removed-from-shop-receipts-over-health-concerns-20221225-p5c8pq.html https://www.smh.com.au/business/consumer-affairs/controversi...
