The Check Clearing for the 21st Century Act - or Check 21 - went into effect October 28, 2004 with the specific purpose of reducing our reliance in the U.S. on paper checks. In essence, Check 21 encourages banks to present and clear checks electronically by allowing them to truncate paper checks in the collection process by creating a Substitute Check. Also known as Image Replacement Documents, or IRDs, Substitute Checks are considered the legal equivalent of a paper check.

While the discussions surrounding this issue had been ongoing for several years, the need for a more streamlined check clearing process became critical in the days following the 9/11 terrorist attacks as literally trillions of dollars were prevented from clearing due to grounded planes. Remote Check Deposit is the first step in a nationwide effort to convert from paper to a completely electronic environment, a process that will likely take many years. In the end, however, Check 21 will result in making the U.S. banking system far more efficient.

Your Responsibilities
Specifically with respect to Remote Check Deposits, businesses will be responsible for:
  • Scanning check images and transmitting deposits electronically
  • Defining procedures for creating, approving and transmitting images to help mitigate the risk of fraud
  • Devising secure storage for original paper checks for a specified number of days (Citibank requires 75 days)
  • Proper destruction of original paper checks using an on-site shredder or bonded disposal service
  • Facilitating employee awareness and providing comprehensive training
