Modoo Designer QR child safety

A necklace that helps a lost child reach a guardian

Modoo Designer Corp. makes engraved jewelry with a QR code for child safety. When someone finds a child wearing the necklace, they scan the code with any phone camera and can contact the guardians the owner registered. myj.ai is the service site for that QR code.

How the QR service works

  1. The owner registers the necklace's QR code in their Modoo Designer account and adds guardian contacts.
  2. A finder scans the QR code and opens a page like the demo below. No app is needed.
  3. The finder asks to contact a guardian. Guardians receive a text alert and can call or chat; location is shared only through that interaction and the phone's permission. The necklace is not a GPS tracker.

The jewelry behind the QR code

Every necklace starts as a customer's own design: a pendant shape, engraved text, a photo or drawing, and optional birthstones. We laser-engrave and ship it from our workshop in Incheon, and the QR child-safety option links the pendant to this service. These are real customer designs from our public catalog.

Consent is collected on the phone verification form inside the account area. You enter your mobile number with its country code, read the SMS notice, and tick a separate, optional checkbox that starts unchecked. The verification code is not sent until you give consent.

Guardian alerts go only to contacts the necklace owner adds in QR settings. The owner confirms that each listed guardian agreed to receive safety alerts, and that confirmation is cleared whenever the contacts change.

Consent checkbox wording (unchecked by default)
