Cardless and Secure ATM Cash Withdrawal for Rural Areas
Authors
Abstract
An imminent revolution in ATM transactions is poised to tackle the shortcomings of
traditional card-based systems. Relying on physical cards exposes users to theft and
misplacement risks, exacerbated by the management of multiple cards. Introducing the
innovative solution: a cardless ATM transaction process. This groundbreaking method
allows users to effortlessly authenticate themselves using their unique fingerprints,
eliminating the need for easily lost physical cards. Authentication involves meticulously
comparing fingerprints with registered data, ensuring stringent security measures. Upon
successful verification, users gain access to their bank accounts, each requiring a specific
PIN. Advanced encryption techniques, such as AES, significantly bolster the security of
this process. Connection between the user's verification device and the ATM is seamlessly
established using Zigbee technology, bypassing the necessity for an internet connection.
Once the correct PIN is input, users can seamlessly conduct transactions, including
withdrawals and deposits. Noteworthy is the system's capability to designate guest users
and grant transaction authorization, ensuring secure transaction approval even in the
absence of the primary user, thereby enhancing peace of mind. The implementation of this
groundbreaking project holds the promise of revolutionizing ATM transactions, enhancing
both security and convenience. Furthermore, its independence from internet connectivity
renders it suitable for regions with poor connectivity or challenging environmental
conditions, underscoring its accessibility and adaptability. In essence, this innovative
system heralds a new era for ATM transactions, delivering heightened security and
convenience, poised to redefine financial transactions.
