SmartMetric, Inc. A fingerprint scan credit card is a type of biometric card that uses a built-in fingerprint scanner to verify the identity of the cardholder when they try to make a payment.

Costco finance chief Richard Galanti told CNN that more people have been sharing memberships since the pandemic in 2020. Costco is testing the scanners at a handful of stores to see if they help.

Costco is cracking down on membership card sharing by requiring all cards to be scanned at the entrance. This new rule will make it harder for people to gain entry using someone else’s card.

The days of sneaking into Costco with someone else's card are coming to an end. Shoppers will have to scan their cards at the entrances of stores, and all guests must be accompanied by a valid member.
