Ensure the light is coming from in front of you, not behind you, such that your face is clearly visible without backlighting
Look directly into the camera, and position yourself just like in a passport photo; making your shoulders and top of the head visible.
Use a simple background, if accessible.
Do not wear a hat or sunglasses when taking the self-portrait.
If you’re wearing prescription glasses on the documents provided; wear the glasses when taking the self-portrait too. If no prescription glasses are worn on the documents, please make sure not to wear one either when taking the self-portrait.
Handwrite the date of the day and the word "CoinCash" on a piece of paper and sign it.
Keep your ID card/passport/driver's license and the paper you've written before in your hand while taking the selfie.
Be careful not to obscure information in documents.
