The mass adoption of digital ID and digital driver's licenses has raised questions about privacy and personal security.

And on top of immediate privacy issues, the expansion of digital ID services does increase the demand for verification in the future. On its website, Apple envisions a world where you can use this digital ID for more than just verifying identity for flights.

Travelers who attempt to fly without a Real ID or passport could be subject to a new airport security screening program that carries an $18 fee. On Thursday the TSA announced another option for travelers who have yet to get their Real ID or are flying without their passport: the modernized alternative identity-verification program.

After two decades of trying to standardize security for ID cards, the feds set a hard deadline of May 7 to convert to a REAL ID or risk staying being denied access to airplanes. If you're wondering if you already made the switch – which you very well may have if you renewed your license in the past couple of years – there are two versions.

The Transportation Security Administration proposed an $18 fine for airport travelers without Real ID or other accepted form of identification.

Fears about Apple's Digital ID are afraid of a boogeyman that the iPhone can't unleash, and concerns about governmental tracking or over-reach because of it are best pointed at other avenues that actually exist.

Where automation replaces local, human assistance, those least able to navigate the systems are most likely to lose out.

Traveling is always a slight production, so when something comes along that can ease the burden on planning even just a little, most folks jump to it. However, not every solution truly addresses the problem well.
