## AI overview

This article examines the security implications of SoftPOS, which turns smartphones into card-present payment terminals. It explains that moving payment functions to mobile devices shifts responsibility to the device, operating system, application integrity, APIs, and runtime environment, and discusses threats including app tampering, reverse engineering, API abuse, credential theft, malware, and bypassed environment checks.

## Source excerpt

As retailers look for faster, more flexible ways to accept payments, SoftPOS is becoming a cornerstone of modern payment strategies. It's expected that by 2027, more than 34.5 million merchants will accept payments through SoftPOS technology. The ability to turn any smartphone into a card-present terminal reduces hardware costs, simplifies onboarding, and supports new use cases like curbside, pop-up stores, and in-aisle checkout.
