FAQ – Mobile Banking & Check Deposit

When depositing a check through The Savings Bank Mobile App, effective immediately, please make sure you use the endorsement listed below:

Your signature AND “For mobile deposit only at The Savings Bank” is required for all checks deposited via TSB Mobile Deposit.

If you deposit a check without this mandatory endorsement, the check may be rejected. You will receive an email notification that your “transaction was rejected during the review” and “Reject Reason: Missing Restrictive Endorsement” at the email address on file for your TSB account.

Is this endorsement required on all checks I deposit at TSB?

This endorsement only applies to mobile deposits and is not required when you visit the bank.

Why is this endorsement required? It’s so much longer than a regular endorsement.

We know the endorsement is long, and we apologize for any inconvenience this may cause you. This longer endorsement is being used to protect your deposits so that items are not accidentally presented a second time at another bank when they have already been deposited via TSB Mobile Deposit.

Can I use the check box in the endorsement area rather than using this new endorsement?

No, the mobile deposit check box and space for the date are for your record-keeping and do not meet the requirement for mobile deposits

Network Support

Mobile Banking only supports TLS 1.2 for app communications. Any device or browser that does not support TLS 1.2 will not be able to connect to Mobile Banking services.

The Mobile banking products can operate on any unrestricted TCP/IP data network. Operation on restricted networks (e.g., where a firewall might be in place) is not guaranteed.

The Mobile Banking product supports the Tier 1 carriers in the U.S., including:

• AT&T©
• Verizon©
• T-Mobile©/Sprint© 
• US Cellular©

Mobile banking support for non-Tier 1 carriers depends on the contractual agreement between the SMS gateway provider (aggregator) and the individual carrier.
