What does upgrading an EFT prompt regarding charges?

Upgrading an EFT (Electronic Funds Transfer) prompt regarding charges typically indicates that there is a nominal fee associated with the upgrade. In this case, a $1 charge is the amount prompted when the upgrade is executed. This reflects a common practice in payment systems, where minor adjustments or enhancements may incur small fees to cover processing or service costs.

It's important to note that the specific amount charged can vary depending on the system's policy and structure, but selecting the amount that actually represents a widely accepted fee for such upgrades—like $1—aligns with standard industry practices for minimal service charges, which helps ensure that users are aware of any costs related to enhancing their transaction capabilities.
