If you enter the waiting area, to your left is the counter for booking the visit but also a window for paying money into the prison bank account. There is a little slip of paper that you are supposed to use to fill in the details. You get this from the same round tables in the middle of the room where you found the Visitor registration form. Unfortunately it is all in Thai. There are four lines. The top line has two spaces for your first name and family name. The second line has two spaces for the prisoner's first name and family name. The third line has two spaces for the amount of money and the section (usually Dan 2 if they are a male prisoner just arrived). The fourth line has two spaces for id card number (you can leave blank) and the cell number. You can also leave that blank if you don't know. Give this slip of paper and the money to the guy behind the counter. He will then write out a receipt to give to you. From experience, we have learned that they don't always know about this deposit. We once did an anonymous donation to a prisoner. But she only found out about it as she was preparing toleave.

This money can be used by the prisoners though they cannot withdraw more than 200 baht per day.  They don't actually touch the money as they are given coupons. These coupons are only valid for 24 hours. There doesn't seem to be a limit to how much money they can have in their accounts. If you cannot go to Thailand, then it might be possible to send money through your embassy. In extreme cases, we might be able to assist you.
