    To access the full suite of features offered by the SBI Digital Rupee application, there are specific eligibility requirements. Primarily, the service is available to individual customers who hold an active savings account with the State Bank of India. During the registration process, the app will verify your identity using the mobile number registered with the bank.

    My personal Facebook profile is locked after I lost the phone that held my two-factor-authentication app. I already went through Facebook’s normal “Forgot password” flow, but because I no longer receive the 2FA code the process stalls and the account remains inaccessible. I need practical, proven guidance—or hands-on support if you have agency access—to get back into the profile without that original authenticator device. Recovering the account must keep all existing data, pages, and business integrations intact. Acceptance will be: • Successful login from my side on a new trusted device • 2FA either restored with a new authenticator or fully disabled by agreement • A short note outlining the exact steps taken so I can repeat them if eve...

    I need a web and mobile app that lets doctors handle every step of a medico-legal case in one place. The core of the build is a secure case-management workflow that opens with a new file, pulls in the patient’s full clinical history, links all supporting legal documents, and keeps conversations with solicitors neatly threaded next to the record.

    I’m putting together a full-stack web application that relies on clean, modern front-end code (HTML, CSS, vanilla JavaScript) and a PHP 8.x back end powered by MySQL. Visitors must be able to register, log in, and see a personalised dashboard, while I manage everything through a protected admin panel. Design needs to feel contemporary—ample white space, balanced typography, and subtle transitions—and the entire experience should resize elegantly down to mobile screens, so solid responsive techniques with flexbox or CSS grid are essential. Only two roles are required for this build: a basic registered user and an admin account. All admin-only routes and features have to be protected with session-based authentication, role checks, and clean redirects. Security is a priori...

    I run a fleet of privately owned ATMs and need a purpose-built cash-filling solution that combines rock-solid security with smooth loading. The core requirements are: • Cash filling mechanism that lets me load notes quickly straight into standard cassettes, minimising downtime and user error. • Integrated security features—tamper sensors, dual-factor access, and an encrypted access log—to protect every refill cycle and create an auditable trail for compliance. This filler will be used only on my private ATM machines, so dimensions, connectors, and software hooks must match the usual off-site, standalone cabinets rather than drive-up or branch-integrated models.
