This is clever - physical tamper evidence + phone-scannable entropy. Like a reusable glitter seal where the pattern is the fingerprint, so you can photo-verify if your backup was touched. For seed storage it's a good detection layer, not protection. Still needs to be with metal backup + geographically separated. Biggest risk isn't someone opening it stealthily, it's fire/flood/corrosion. But for checking if your safe deposit or family member peeked? Perfect use case. Reusable is key - most tamper seals are single-use so people stop checking. If you can reseal and re-scan with your phone daily, you'll actually do it.
