RooCards's answer:
RooCards is built for people who want a simple, private, and fast way to keep everyday store cards, loyalty cards, membership cards, barcodes, and QR codes on their iPhone.
Unlike many card wallet apps that focus only on basic barcode storage, RooCards also supports home screen widgets, card grouping, custom card images, barcode and QR code access, iCloud backup, and Apple Wallet export for supported cards.
The goal is not to replace every payment or wallet app. RooCards is designed to make everyday cards easier to find, open, scan, and organize when you are at the checkout, gym, pharmacy, grocery store, library, or local shop.
RooCards's answer:
People should choose RooCards if they want a lightweight iPhone app focused on everyday card access without unnecessary complexity.
RooCards is especially useful for users who have many physical loyalty cards, barcode cards, membership cards, gift cards, or QR codes and want to keep them organized in one place. It offers fast search, categories, pinned cards, widgets, card customization, and Apple Wallet support for eligible cards.
It is a good fit for users who care about quick access, clean organization, and privacy. RooCards does not require users to create an account just to manage their own cards.
RooCards's answer:
RooCards is mainly built for iPhone users who still carry or regularly use physical store cards, loyalty cards, membership cards, gift cards, barcode cards, and QR codes.
The primary audience includes shoppers, families, students, gym members, pharmacy customers, grocery shoppers, library users, and anyone who wants to reduce the number of physical cards in their wallet.
It is also useful for people who want faster access to frequently used cards from their iPhone Home Screen using widgets.
RooCards's answer:
RooCards was created to solve a small but common everyday problem: people often have too many physical store cards, loyalty cards, barcode cards, and membership cards, but they still need quick access to them at checkout or when visiting local stores.
Many users already use Apple Wallet, screenshots, notes, or photos as a workaround, but those methods can become messy and hard to search. RooCards was designed as a cleaner, more focused card wallet for iPhone users who want to store, organize, customize, and quickly open their everyday cards.
The product started from a practical need: make everyday cards easier to find and scan, without forcing users into a complex account-based system.
RooCards is a simple wallet for loyalty cards, membership cards, barcodes and QR codes. The most useful feature is the ability to add eligible cards to Apple Wallet, so frequently used cards are easier to access on iPhone.
It also makes everyday checkout faster by letting you pin cards, search quickly, use widgets, and open scan-ready barcodes or QR codes without digging through screenshots or store apps. A practical utility for keeping store cards ready when you need them.

(G)NATS can do millions of messages per second and is the right tool for the job (either that or NSQ). Redis isn't even the fastest Redis protocol implementation, KeyDB significantly outperforms it. Source: over 3 years ago
Bit.ly's NSQ is also an excellent message queue option. Source: over 3 years ago
Queue consumers are interesting because there are many solutions for them, from using Redis and persisting the data in a data store - but for fast and scalable the approach I would take is something like SQS (as I advocate AWS even free tier) or NSQ for managing your own distributed producers and consumers.
