Which of the following does not involve an image for check processing?

The check conversion process is focused on transforming paper checks into electronic forms for easier processing and payment by using various methods, including converting the information from the check into a digital format. This does not specifically require creating or utilizing an image of the check itself; rather, it emphasizes the transformation of data associated with the check for electronic processing.

In contrast, the other processes mentioned all involve images in some capacity. The check imaging process is essentially about capturing an electronic image of the physical check, allowing for storage and processing without the need for the physical check. The remote data capture process involves scanning checks at the point of deposit, where an image is created for submission to the bank. Magnetic Ink Character Recognition, while it does use magnetic ink to read the numbers on the check, still relies on the check's written structure to process the information typically in conjunction with an image for verification.

Thus, the check conversion process distinctly stands apart as it does not necessitate an image, adhering solely to the data transformation for electronic payment.
