Summarize this article in one sentence.
In many US states, for example, you must establish a bank account for your charity if you want to receive donations from the public. Do some research online to find out if this is necessary where you live. Put a name on the account to be sure it is clear for tax purposes. For example, if you are raising funds for a child named Susan Baker, who is getting treatments for cancer, name the account something like the “Susan Baker Donation Fund.” Store the cash and checks you receive in the lockbox. Keep change in the lockbox as well or have the person in charge of donations keep change in a fanny pack or cash bag. If you will receive donations by check, print or write a large, clear sign letting donors know to whom the checks are payable that you can place somewhere visible during the event. Get a credit card machine or a mobile payment device, such as Square, that works with mobile phones if you want to receive payments by card.  Be aware that Square has fees attached and credit card companies take a percentage of each sale as payment. You can also set up a PayPal account to help you take donations.

Summary:
Open a bank account if it is required in your area. Get a lockbox and change if you plan to receive cash and check donations. Acquire the right equipment if you want to receive credit card payments.
