# 防伪验证 vs NFC Trace

The clearest difference is update cadence: NFC Trace at every 3 weeks against 防伪验证's every 12 months. 防伪验证's advantage is iOS requirement (11.0 vs 16.0.2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

防伪验证 ships an update every 12 months, NFC Trace every 3 weeks. The most recent releases landed on October 19, 2026 and October 9, 2026 respectively.
