I must know your identity to prevent fraudulent payments.
After initiating trade:
Send me a photo of your credit card with your name and last 4 digits of the card visible. The other information can be covered for your privacy.
Send me a photo of your ID that shows your full name matching the name of your credit card. If your ID does not have your signature then send me a photo of the back of your credit card that does show your signature.
On a piece of paper write today's date alongside the text, "I authorize my card ending in XYZ to be charged by backatco for $C." Replace XYZ with the last 4 digits of your credit card. Replace the C with the amount of the transaction. Sign the paper with your signature. The signature must match the signature on either your ID or the back of your card. Take a selfie of yourself holding the piece of paper close to your face. Your face must be fully visible in the photo.
After I review the information if it is satisfactory I will send you a link where you can complete the payment. If you do not follow these instructions then your trade request will be canceled.
If these terms are not acceptable to you then do not initiate a trade.
