Essential Things to Look for in an iOS Fax Solution
When selecting your preferred tool, consider the following key factors:
- Transmission Security: Check if the system uses SSL encryption for files in transit, or AES-256 for files at rest.
- Pricing System Check: Be sure to verify whether a monthly contract or a pay-per-credit model aligns with your actual monthly volume.
- Optical Page Quality: Look for auto-cropping scanners that clean up background shadows from document images before transmission.
