Troubleshooting

Q: What if someone suspicious looking is not selected for screening by the app?

A: It is possible that the app will at times provided an unwanted result. If this occurs simply rotate the iPad by 180 degrees.

Q: What if my particular situation requires more than 2 direction arrows?

A: We currently enable two directions for free. If more than two direction arrows are required for your particular use case, please contact us at [email protected] to learn more about our paid plans.

Q: I paid an extra $336,000 for an extra direction for my arrow, but now I don't need it.

A: TSA Engineering does not reimburse users for unused direction arrows.

tsa's Issues

slight favor for direction left?

Please check my math, but from my understanding, Math.random has a range of 0 (inclusive) and 1 (exclusive). So the max number possible is 0.999... repeating. By checking random > 0.5 to set a direction right, aren't you favoring direction left by a slight margin since the smallest value for direction right would be .5000...1 repeating? If so, random >= 0.5 would fix this.

Math.random() is not cryptographically secure

For something where you don't want a possible attacker to have any knowledge of the upcoming lane, the randomizer needs to be cryptographically secure.

Thankfully, this is easy to fix by just using https://developer.mozilla.org/en-US/docs/Web/API/RandomSource/getRandomValues instead of Math.random().
