DIY IoT Payment System With Google Firebase (KhadashPay Firebase Edition V1.0)

[Northstrix]

Hello. Let me introduce you to the payment system that I've developed

It doesn't require the seller to buy an expensive payment terminal and pay fees for each transaction (unless of course, your business becomes so successful that you exceed the Spark Plan offered by Google), and it doesn't require the clients to pay maintenance fees. Moreover, with KhadashPay, clients can create multiple accounts using a single RFID card, provided they use a different PIN for each account. The account information is encrypted and securely stored in the cloud. Additionally, KhadashPay has useful features such as "Belonging Check" and Integrity Verification.
