Fraud Protection for Debit Cards

Lyon County State Bank utilizes a Fraud Monitoring Service that is on guard for customers 24 hours a day, 365 days a year.  Our Fraud Monitoring Service provides real time scoring and decisions on debit card transactions.  Temporary account blocking for transaction validation helps protect against fraudulent card transactions.  To obtain the best level of fraud monitoring, insure that the bank has your valid phone number and email address on file.

smsGuardian – Text Alert Fraud Protection

In addition to Fraud Protection, Lyon County State Bank is proud to offer an additional text alert service for enrolled debit cards.  This service is free³ of charge and provided by smsGuardian.  Upon enrollment, cardholders will receive a text message when the enrolled debit card is involved in a transaction often associated with fraudulent activity.  The text message will contain the last four digits of the card used, the name of the merchant or transaction, and the dollar amount.  If the transaction is legitimate, no further action is necessary.  If the transaction is fraudulent, simply reply to the alert text message as directed and the debit card will be permanently frozen.

To cancel or opt-out of this service, simply reply to a Guardian alert with the word “stop” or unsubscribe entirely by visiting smsGuardian’s website.
