ATM commonly dispensed by cash machines
Bars are scaled to face value on a log scale, not to physical size. Colours are the issuer’s own. Converted at mid-market reference rates; what a counter pays is always less.

Getting cash
US cash machines overwhelmingly dispense $20 notes; some offer $50 and $100. All US banknotes are the same size and carry no tactile markings, so denominations cannot be told apart by touch.

Security features are designed to be checked by hand in a few seconds, tilt it, feel it, hold it to the light. These are the features Federal Reserve publishes for the US dollar.
