Currency strap

This article is about a currency packaging device. For the mechanism used to regulate the exchange rate of a given currency, see currency band.

A currency card, cash strap, currency band, money band, banknote strap or bill strap is a simple paper device designed to hold a specific denomination and number of banknotes.^[1] It can also refer to the bundle itself.^[2]

A stack of 100 United States $2 bills, secured with a green banknote strap indicating the denomination and total amount in the stack.

Two stacks of 100 20 euro notes and one stack of 100 50 euro notes delivered to a bureau de change by G4S.

In the United States, the American Bankers Association (ABA) has a standard for both value and color. Note that all bills greater than $2 only come in straps of 100 count. The colors allow for quick accounting, even when the bills are stacked, such as in a vault. Special striped bands are used for straps exclusively containing star notes.

History

A simple homemade currency strap holding 80 $1 bills, made from a loop of paper secured with sellotape

Bundling money together with a simple elastic or paper device is as old as paper currency itself. However, measured and standardized straps are a relatively new idea. For example, until the mid-1970s, The US Federal Reserve counted bills by hand. That is, they employed 55 currency counters whose job it was to count as well as, by touch and feel, authenticate bills.^[2] However, as the amount of currency in circulation increased, they found that they needed a more efficient way to count currency. To help the Currency Counting staff keep up, the Bank began strap-sorting the $1 to $20 notes. Straps were visually inspected and weighed against a counterweight equal to the paper mass of 100 genuine U.S. notes. Currency straps have even helped catch the culprits in bank robberies, like the Dunbar Armored Robbery in 1997, after one of the culprits decided to pay a real estate broker with a still-strapped bundle of notes.
