Many companies, communities and hospitals use tokens as comprehensive way to control their parking. A system with tokens in a barrier is cheap, safe, reliable and easy to use. It does not depend on sophisticated software or electronics that depend on networks and are subject to downtime.
Parking barriers are often outdoor, so corrosion free tokens are most common.
The recommended token is different for every location. If security requirements are lower, a grooved token with mechanical validator could be the best option. If security requirements are higher, a secure alloy in an electronical validator could be the preferred choice.
