POC Coins — your payment tokens
1 POC Coin = $1 USD · Safe · Trusted · Verified
1 POC Coin always equals exactly $1 USD. You always know what you will earn.
Coins are locked until the child is home and the review is complete. You can see them — but not spend them yet.
Coins are not tradeable. They belong only to you. Only you can redeem them.
Accumulate across cases. Each completed child adds coins to your wallet. They build up.
When the child is home and reviewed — coins convert to cash automatically. M-Pesa notification on your phone. No forms. No bank. No waiting.
Section 3 — The three videos · Send all to POC WhatsApp
Three videos. One phone call. That is everything you need to film.
Surgeons do not film. Hospital staff or the outreach worker films at the hospital. Grace films the child at home.
1
Grace finds the child in Kigoma or the surrounding area. She films them before any treatment has started. She sends the video to the POC WhatsApp number with no caption.
The video must show:
☑ The child's face — clearly visible☑ The child's condition — visible
☑ Grace on camera — say your name
☑ Say where you are
☑ Say today's date
☑ Say the child's name and age
Caption
No caption — leave it blank. No caption means new child.🪙
POC Coins drop to Grace immediately. Locked in her wallet. She can see them. Cannot spend yet. They are hers when the child is home and verified.
