The Privacy Friendly PIN Mnemonic application can be used to find out strategies to memorize a Personal Identification Number (PIN). It belongs to the group of Privacy Friendly Apps.
After entering the PIN, the application displays up to five strategies or memorizing the PIN:
- It draws the shape on the number pad and highlights the numbers corresponding to the PIN.
- It determines whether the PIN forms a word using the letters of the number pad.
- It checks if the PIN is in year or date format
- It checks if the PIN underlies a mathematical rule
- It provides symbols for inventing a little story to facilitate memorizing the PIN.
The application also provides the possibility to practice entering the PIN keeping the prefered mnenomic(s) in mind.
Our Privacy Friendly App differs from other applications with respect to two aspects:
- No permissions
The Privacy Friendly PIN Mnemonic App does not use any permission.
- No advertisement
The Privacy Friendly PIN Mnemonic App completely relinquishes advertisement.
More information and the most important hints regarding PIN management can be found in our flyer.
