## A2Calc Description
A2 Small Format Interchangeable Core Calculator

---Programmed by a Locksmith, for Locksmiths---

Automatically calculates the pinning chart for A2 SFIC. Built for 6 or 7 pin systems, however, less can be achieved by using a decimal to erase a chamber.

Minimum of a control and master key are required to make a chart. Additional change key available for all devices; 2 change keys available for 4" (and above) screen devices.

Randomize function will generate completely random charts each time it is triggered.

"Lock/Unlock" toggle disables/enables all inputs and functions to prevent unwanted/lost changes.

Control Finder is an added bonus by reverse engineering a core to determine the control key's bitting. This is perfect when needing to remove multiple cores in a building when the control key has been lost. There are two methods for achieving the control key: 1. using the master, control, and bottom pins, or 2. using only the top/driver pins.

Up to 16 different projects can be saved at any one given time.

All projects are encrypted and protected with a passcode.

AirPrint or Email projects with a single tap.

Compatibility: iPhone / iPod touch on iOS 8.0 or later and iPad on iOS 12.0 or later.
