Welcome to the Seller Community @SBASON!
Yes Square works with Visa as well as most US-issued debit and credit cards that have the MasterCard, Amex, Discover, JCB and UnionPay logos. Square is also PCI Compliant and your customer's card information is encrypted and securely stored.
I hope this helps but if you have any additional questions about using Square let me know!
