With the POSTIDENT app, you can verify your identity conveniently and simply by means of your smartphone. Depending on which of our partner companies you carry out this identification process, you can verify your identity either via POSTIDENT by videochat, POSTIDENT by eID (with your national identity card or the electronic residence title), or fully automatically by creating images of your ID document and profile. With the eID function or the automated verification of your ID document you can verify your identity quickly and securely at any time. Your data will be checked by call center employees of Deutsche Post AG in all further identification procedures. Our employees are available to you from Mondays to Sundays in the hours from 8 AM to 10 PM. In addition, you can retrieve the POSTIDENT coupon for identification in your post office directly via the POSTIDENT app and therefore do not need to print it out anymore. The identification procedures are compliant with the law, secure and completed in just a few steps. Simply enter the transaction number that you have received from either our partner company or us. The POSTIDENT app will then execute the procedure. At POSTIDENT by videochat, a Deutsche Post employee will explain additionally in detail how the procedure works. The POSTIDENT app is optimized for iPads and iPhones with iOS 17 or higher.

Verdict
The clearest difference is rating: POSTIDENT at 4.8 against AlphaESS's 2.9. POSTIDENT also leads on ratings volume (4.7K vs 7) and review sentiment (43% vs 26%). AlphaESS's advantage is update cadence (weekly vs monthly) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
