tap2go is a free Android app designed to convert any smartphone equipped with an NFC module into a contactless payment terminal. It supports payments via bank cards and popular mobile wallets such as Google Pay, Apple Pay, and Samsung Pay, allowing merchants to accept payments seamlessly. The app integrates with various other applications, enhancing their functionality by enabling secure payment processing directly from the smartphone.

Security is a key feature of tap2go, as it utilizes a certified payment kernel that complies with PCI DSS Level 1 standards. This ensures that no payment data is stored on the device during transactions, with all information transmitted in an encrypted format. The payment process is straightforward: customers simply tap their card or mobile device to the merchant's smartphone, completing the transaction with ease and receiving an electronic receipt.
