MasterCard Identity CheckMasterCard Identity Check Keeping your account safe and secure is our highest priority. We continue to partner with SHAZAM, our debit card processor, and will implement additional authentication known as Mastercard Identity Check. This new requirement will begin on August 8, 2023 for online/web transactions when the online merchant is signed up for this product. When both the e-commerce online merchant and First New Mexico Bank, Las Cruces participate in Mastercard Identity Check, the transaction will go through a risk-based authentication. As the cardholder, you will be asked to identify yourself by receiving a One-Time Passcode (OTP) via text message*. Once received, you will enter this code on the online checkout screen with SHAZAM’s logo. At this time, the code will not be required for ‘in-person’ transactions. If an invalid OTP is entered in the checkout screen, the transaction will not be authenticated. If three (3) consecutive invalid OTPs are entered into the checkout screen, your card will be blocked at all Identity Check participating e-commerce online merchants. To unblock your card, please contact First New Mexico Bank, Las Cruces Monday – Friday from 8:00 am – 5:00 pm. If you have any questions, please call First New Mexico Bank, Las Cruces at 575-556-3000. and be sure to log into online banking regularly to see all of your account transactions. *Standard text messaging fees may apply through your mobile phone carrier.
