Frequently asked questions
How is it different from the sewn-in label?
The sewn-in label is sewn in as the garment is made. The patch is heat-pressed onto finished garments. Both use the RFID-X sensor.
Do shoppers need an app?
Shoppers download the FAI-X app, then tap their phone to see whether the garment is genuine and view its details. On an iPhone, hold the top of the phone to the patch; on a Galaxy, the back.
Can it be washed?
The sensor is waterproof and heat-resistant. How it holds up to washing depends on the fabric and wash conditions, so we test it under your actual conditions before rollout and tell you the results.
Can I change the patch design?
Beyond the X³ logo and heart in the photos, we work out the design and quantity with you.
