# How MICR Check Scanning Works

**E-Check Verification Form**

- A Scan button is displayed at the bottom of the E-Check Tendering verification form.
- This button initiates a scan using the MICR reader attached to the (configured) register.
- The scan button is enabled when the window first opens; it is disabled during a scan; and re-enabled once a scan either completes or times out.

**MICR Scanning Initialization**
- When the user clicks a tender type of E-Check, the IDI platform checks to see if a MICR reader is configured.

**MICR Scan Response**

The following information is recorded in the IDI platform when it receives notification from the MICR reader that a check has been scanned:
- ABA Routing number
- Account Number
- Check Number

The Bank account type is set to Checking; the Bank Name and Account Holder Name fields are cleared, and the Drivers License Number field and Driver License State fields remain.
