GetQRcard is a digital business card and QR email signature service for professionals, freelancers, nonprofits, schools, local authorities, teams, and organizations. It is developed and operated in Liège by Le Chemin Numérique ASBL, a registered Belgian nonprofit.

Create a mobile-friendly contact card in minutes and share it with one QR code. The same QR can appear on a printed business card, badge, flyer, sign, or email signature. Recipients scan it on iPhone or Android, view the details, and save the contact without installing an app.

The printed QR code stays the same when the card owner updates a phone number, email address, job title, company, photo, location, website, or social link.

Key features

  • One free personal digital business card
  • Editable QR destination without reprinting
  • vCard contact saving
  • Matching QR email signature
  • No app required for recipients
  • English and French interfaces
  • Scan totals, device and country breakdowns from the beginning
  • Daily scan chart for 30 days on the free plan and 90 days on the annual plan
  • Bulk card creation from a staff spreadsheet
  • Centralized card and email signature management for organizations
  • No advertising on free or paid cards

The annual confirmed plan costs €15/year and adds unlimited cards, bulk generation, hosted PDF documents, and an account-holder name confirmed through the payment provider. If the subscription ends, the first card remains active and editable free of charge; additional cards are paused rather than deleted.

GetQRcard is seeking practical, honest feedback from users in Belgium, Canada, and worldwide.

s3-lambda features and specs

  • Batch processing of S3 objects
    s3-lambda provides a straightforward way to perform batch operations on large numbers of S3 objects, enabling map, filter, and reduce-style processing over entire S3 buckets or prefixes without writing boilerplate code.
  • Familiar functional API
    The library uses a functional programming paradigm with operations like map, filter, and reduce, making it intuitive for JavaScript developers to process S3 objects using patterns they already know.
  • Built-in concurrency control
    s3-lambda handles parallel processing of S3 objects with configurable concurrency, allowing users to control how many operations run simultaneously and avoid overwhelming AWS resources or hitting rate limits.
  • Context-aware operations
    The library provides a context object within each operation that includes useful metadata about the current object being processed, simplifying access to S3 object properties during transformations.
  • Easy integration with Lambda
    Designed to work seamlessly within AWS Lambda functions, making it straightforward to set up event-driven, serverless pipelines for processing large volumes of S3 data without managing infrastructure.

Possible disadvantages of s3-lambda

  • Unmaintained project
    The repository appears to be no longer actively maintained, with limited recent commits and unresolved issues, which raises concerns about long-term reliability, security patches, and compatibility with newer AWS SDK versions.
  • Limited documentation
    The project's documentation is relatively sparse, lacking comprehensive examples, edge case handling guidance, and detailed API references, which can make it challenging for new users to adopt effectively.
  • AWS SDK version dependency
    The library depends on an older version of the AWS SDK for JavaScript, which may conflict with projects using the newer AWS SDK v3 and could miss out on performance improvements and features in updated SDKs.
  • Limited error handling flexibility
    The built-in error handling mechanisms are relatively basic, and handling partial failures or implementing sophisticated retry logic for individual object operations requires additional custom code from the developer.
  • Narrow scope of functionality
    The library is tightly focused on S3 object processing and does not integrate with other AWS services or provide utilities beyond basic map/filter/reduce operations, limiting its usefulness in more complex data pipeline scenarios.

GetQRcard features and specs

  • Permanent editable QR code
    Keep the same QR code while updating contact details anytime.
  • Digital business card
    Mobile-friendly card with one-tap contact saving and no app required.
  • Professional email signature
    Create a matching email signature for consistent professional branding.
  • Bulk card creation

Questions & Answers

As answered by people managing s3-lambda and GetQRcard.

What makes your product unique?

GetQRcard's answer:

GetQRcard combines a free digital business card, a matching professional email signature, and one permanent QR code. The code never needs to be reprinted: users can update their contact details anytime, and recipients can save them on iPhone or Android without installing an app. Personal use stays free for life; organizations only pay for bulk creation and centralized management.

Why should a person choose your product over its competitors?

GetQRcard's answer:

Choose GetQRcard if you want a simple, app-free experience with no recurring cost for personal use. You can create a card in minutes, share it through a permanent QR code, update details without reprinting, and give recipients one-tap contact saving. It also includes a matching email signature. For teams, bulk creation and centralized administration are available when needed.

How would you describe the primary audience of your product?

GetQRcard's answer:

GetQRcard is designed for professionals, freelancers, consultants, entrepreneurs, job seekers, event attendees, nonprofits, associations, and small teams that want to share accurate contact details quickly. It also serves organizations that need to create and manage many employee cards and email signatures from a staff list. The interface is available in English, French, Dutch, Spanish, and Chinese.

What's the story behind your product?

GetQRcard's answer:

I built GetQRcard because it was a service I personally needed and could not find in the form I wanted: simple, app-free, and genuinely free for individual users. A digital business card should not become obsolete when a phone number or job title changes. That led to the permanent QR code and editable contact page. To keep personal use free, the business model is limited to paid organizational needs such as bulk creation, centralized administration, and large-scale email signature deployment.
