Bitcoin ATM (Chicago)
This is a two-way machine (can buy and sell Bitcoin) and it is located at Cassava in Chicago: 3338 North Clark Street Chicago IL, 60657. They accept Bitcoin and make amazing empanadas and smoothies if you are able to make a visit." (from reddit).
The machine will initially ask you for your phone number and send an SMS as an identity check. After this screen you are free to transact up to $3000 on either buying or selling Bitcoin. After the $3000 limit is reached, we require you to scan a piece of government-issued ID. This process is simple, fast, and easy if you wish to transact over a certain amount.
The Bitcoin ATM is operated by Midwest Bitcoin.
