You fill in a short and simple questionnaire to provide some details about the recipient of the card, like pet or children's names, wedding anniversaries, etc. The puzzle will then be built specifically according to the details you enter, personally tailored for the recipient. When receiving the gift, the recipient scans a QR code or types their unique identification number and begins their special challenge, interesting and fun, which is built on the details you provided. Your recipient cracks the code. Your message is unlocked and finally revealed. Warm and fuzzy feelings capture the heart. A fun Israeli idea! https://whosent.me/
