We received a proposal from a customer who uses “Jell Nail QR Code Stickers” for a new way to use them. Specifically, he suggested that QR Code stickers could be used on canes, watch belts, and clothing belts, in addition to fingernails.
While we appreciate the suggestion, we do not recommend the use of QR Code Stickers on anything other than fingernails. The reason for this is that the surface of a fingernail is relatively flat and hard, and we have tested the durability of the seals many times, but the materials and shapes of a cane, watch belt, or clothing belt vary widely, and it is difficult to test under all circumstances.
