| 1 | # FT-10: Time to read |
| 2 | |
| 3 | <!-- Generated from field-tests/suite.json by tools/field_tests.py. Edit the JSON, not this file. --> |
| 4 | |
| 5 | **Category:** Speed · **Time:** about 10 minutes · **Run it and see results:** [https://openckey.org/tests/test?id=FT-10](https://openckey.org/tests/test?id=FT-10) |
| 6 | |
| 7 | ## What it checks |
| 8 | |
| 9 | In ordinary conditions a CKey reads in under 2 seconds from pointing the camera. |
| 10 | |
| 11 | ## Why |
| 12 | |
| 13 | Speed decides whether people keep using a code. The decoder's speed on real phones has not been measured yet; this collects the first numbers. |
| 14 | |
| 15 | ## Test codes |
| 16 | |
| 17 | Print or open the sheet at [https://openckey.org/tests/sheet?id=FT-10](https://openckey.org/tests/sheet?id=FT-10). It is drawn by the CKey web SDK from the values below. |
| 18 | |
| 19 | | Code | Size | Version | Level | Layout | Style | Holds | |
| 20 | |---|---|---|---|---|---|---| |
| 21 | | A | 2.0 in | smallest that fits | M | standard | plain | `https://openckey.org/t/FT10-A` | |
| 22 | |
| 23 | ## Set up |
| 24 | |
| 25 | 1. Print the test sheet at 100% scale; the code is 2.0 inches wide. |
| 26 | 2. Use ordinary indoor light. Open the reader and leave it on the camera view. |
| 27 | 3. Use a stopwatch, or a second person to time. |
| 28 | |
| 29 | ## Steps |
| 30 | |
| 31 | 1. Point away from the code, then start the stopwatch as you point at it from about 20 cm. |
| 32 | 2. Stop it when the result appears. |
| 33 | 3. Repeat 10 times and record each time. |
| 34 | |
| 35 | ## What to record |
| 36 | |
| 37 | - **Seconds to result** (s), number, required. For each of: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. |
| 38 | |
| 39 | Every report also records the device, operating system, reader and its version, and the printer or screen. |
| 40 | |
| 41 | ## How to grade it |
| 42 | |
| 43 | - **Pass:** The median of the ten times is under 2 seconds. |
| 44 | - **Partial:** The median is 2 to 5 seconds. |
| 45 | - **Fail:** The median is over 5 seconds, or some attempts never read. |
| 46 | |
| 47 | ## Report a result |
| 48 | |
| 49 | - On openckey.org: [https://openckey.org/tests/test?id=FT-10](https://openckey.org/tests/test?id=FT-10), with optional photos. |
| 50 | - On GitHub: [open a field-test report](https://github.com/clearkeysolutions/ckey/issues/new?template=field-test-report.yml&title=%5BFT-10%5D+) and choose FT-10. |
