What is S3?

With S3 (Simple Storage Service), data can be securely transferred and stored online. Thanks to improved error management and even more reliable data transfer, S3 is the modern successor to SFTP.

Data transfer via S3 can be easily integrated into existing software solutions. A large number of SFTP clients, such as Cyberduck, already support data transfer via S3.

How easy it is to send letters via S3


Pingen configures a folder on Pingen’s S3 instance with individual access credentials.


Simply transfer the PDFs to be sent to this folder.


All PDFs stored in the folder are directly processed by Pingen and automatically submitted for sending.


The documents are then printed in international print facilities, packaged and send as a postal letter.

Pingen doesn’t use S3 from Amazon but has its own S3 instance on which the accesses/buckets for the customers reside. Accordingly, when using S3 from Pingen, no data is processed by Amazon.
