@reboot888 tel him features for 20

, at Tue Apr 13 18:11:18 2021 GMT+0700:
$20 contains same security features as the $50 and $10.

at Tue Apr 13 18:11:25 2021 GMT+0700:
Magnetic ink in a specific pattern

8, at Tue Apr 13 18:11:48 2021 GMT+0700:
OVI on bottom right and non variable, but still mica pigment powder type star.

r, at Tue Apr 13 18:12:25 2021 GMT+0700:
Security strip made from a polymer, laced through the paper during manufacture that has letters/words/images embedded using a metallic foil that is detectable by certain types of scanners.

8, at Tue Apr 13 18:12:51 2021 GMT+0700:
Visible when held up to light in different locations depending on denomination. For the $20, far left.

t8, at Tue Apr 13 18:13:04 2021 GMT+0700:
Strip glows under UV, different colors for different denominations.

Send the photos

reboot888, at Tue Apr 13 18:13:19 2021 GMT+0700:
$20 is green under UV on the strip. Both externally and when UV light is held to back

8, at Tue Apr 13 18:14:02 2021 GMT+0700:
Serial number algorithm is as follows:

8, at Tue Apr 13 18:14:11 2021 GMT+0700:
PL26221241 B

reboot888, at Tue Apr 13 18:14:13 2021 GMT+0700:
L12

reboot888, at Tue Apr 13 18:14:17 2021 GMT+0700:
P = issued date

8, at Tue Apr 13 18:14:25 2021 GMT+0700:
L = federal reserve bank 1 through 12

8, at Tue Apr 13 18:14:34 2021 GMT+0700:
L12 = Matching the L above it always

8, at Tue Apr 13 18:14:44 2021 GMT+0700:
Cannot have L6. Only L12. A1 B2 C3 D4

8, at Tue Apr 13 18:15:30 2021 GMT+0700:
Each plate used has a specific number. This is found on the top right of the note along with the column letter indicating which column the note was made from. On the bottom left the specific Row/Column are shown.

reboot888, at Tue Apr 13 18:15:40 2021 GMT+0700:
Bottom right of back contains back plate number

reboot888, at Tue Apr 13 18:16:04 2021 GMT+0700:
Sec

reboot888, at Tue Apr 13 18:17:18 2021 GMT+0700:
Black ink all done with intaglio press

reboot888, at Tue Apr 13 18:18:21 2021 GMT+0700:
Intaglio press applies large pressure to plates that are engraved. Multiple ways to make plates. CNC is possible, as well as photosensitive plates similar to making stamping or screen printing materials but with metal. Laser ablation is possible. The black lines should be cut into the plate so that the plate is inked, wiped clean leaving the ink in the lines.

88, at Tue Apr 13 18:18:38 2021 GMT+0700:
Pressure is applied causing the paper to sink into the lines picking up the ink

Getting back to specific security features

, at Tue Apr 13 18:19:23 2021 GMT+0700:
It was unintentional, but now common for the collar to be checked for raised ink

8, at Tue Apr 13 18:19:35 2021 GMT+0700:
This is done by scratching your finger up and done across the lines under the portrait face

8, at Tue Apr 13 18:19:49 2021 GMT+0700:
Feeling the ridges of the ink raised up, a side affect of Intaglio Printing




8, at Tue Apr 13 18:20:58 2021 GMT+0700:
The top right says FW H 36

8, at Tue Apr 13 18:21:06 2021 GMT+0700:
This means it was produced in Fort Worth Texas

8, at Tue Apr 13 18:21:20 2021 GMT+0700:
The H means it was Column H of the full plate, first Column being A

8, at Tue Apr 13 18:21:33 2021 GMT+0700:
Series 2006 is the year the note was designed, not printed.

8, at Tue Apr 13 18:21:43 2021 GMT+0700:
Coins show the mintage year, bills show the design year.

8, at Tue Apr 13 18:21:48 2021 GMT+0700:
If there are two designs in one year, it will say 2006-A

8, at Tue Apr 13 18:22:01 2021 GMT+0700:
Notice the "star" in the serial number

8, at Tue Apr 13 18:22:14 2021 GMT+0700:
This designates that this is a replacement note for a note that was destroyed due to a manufacturing error.

8, at Tue Apr 13 18:22:32 2021 GMT+0700:
They are less common but no reason not to be included in the algorithm for generating the serial numbers.

8, at Tue Apr 13 18:22:46 2021 GMT+0700:
These numbers are trained to bank staff and LE

8, at Tue Apr 13 18:22:56 2021 GMT+0700:
They must be correct, as not only are they trained to people, money counters are programmed to spot them.

8, at Tue Apr 13 18:23:06 2021 GMT+0700:
Failing at this is the easiest give away.

8, at Tue Apr 13 18:23:14 2021 GMT+0700:
Serial NUMBERS are sequential in nature.

8, at Tue Apr 13 18:23:25 2021 GMT+0700:
Literally starting from 00000001

8, at Tue Apr 13 18:23:52 2021 GMT+0700:
The final letter is some what of a checksum, and will cycle from A - Z if necessary to repeat the same Issued Year and Federal Reserve Bank




8, at Tue Apr 13 18:24:05 2021 GMT+0700:
Note the bottom Left F2

8, at Tue Apr 13 18:24:20 2021 GMT+0700:
This means it was Column F, and you this will always match the letter on top right.

8, at Tue Apr 13 18:24:32 2021 GMT+0700:
FW is just an indicator of printing location, and irrelevant otherwise.

8, at Tue Apr 13 18:24:40 2021 GMT+0700:
2 means position 2

8, at Tue Apr 13 18:24:43 2021 GMT+0700:
Row 2













8, at Tue Apr 13 18:26:08 2021 GMT+0700:
Nice, check this out.

F2

8, at Tue Apr 13 18:26:56 2021 GMT+0700:
Means that note was literally stamped from column 2 row F on this chart

8, at Tue Apr 13 18:27:22 2021 GMT+0700:
Shit that link outlines at least half of what I just went over...

8, at Tue Apr 13 18:27:49 2021 GMT+0700:
The microprinting on the $20 is extensive

8, at Tue Apr 13 18:27:58 2021 GMT+0700:
Not counting the color microprint done with offset

8, at Tue Apr 13 18:28:16 2021 GMT+0700:
We have black bottom left to the right of the 0 in 20




8, at Tue Apr 13 18:29:06 2021 GMT+0700:
The feature I am about to explain is the biggest stopper for automated machines

8, at Tue Apr 13 18:29:22 2021 GMT+0700:
This is done using Infrared reflective ink







8, at Tue Apr 13 18:29:46 2021 GMT+0700:
Different stripes position and width indicate denomination

8, at Tue Apr 13 18:30:06 2021 GMT+0700:
It is used by the machines to easily read this information as the bill passes through




8, at Tue Apr 13 18:30:17 2021 GMT+0700:
Obviously you know this

reboot888, at Tue Apr 13 18:30:20 2021 GMT+0700:
But

reboot888, at Tue Apr 13 18:30:26 2021 GMT+0700:
These should work in a way so that you can also

reboot888, at Tue Apr 13 18:30:34 2021 GMT+0700:
Put the light to the back of the bill and clearly read the text visible

8, at Tue Apr 13 18:31:01 2021 GMT+0700:
You must be careful not to use any fluorescents in anything that you do.

, at Tue Apr 13 18:31:13 2021 GMT+0700:
You want everything to be UV dull

8, at Tue Apr 13 18:31:24 2021 GMT+0700:
The paper the ink, nothing should "glow" under uv light

8, at Tue Apr 13 18:31:43 2021 GMT+0700:
The reflectiveness of the paper using UV light is the most basic and common security feature found on money counters

8, at Tue Apr 13 18:31:55 2021 GMT+0700:
When the money counter says it has UV detection, this is what it means, not the UV ink on the strip

8, at Tue Apr 13 18:32:26 2021 GMT+0700:
It bounces UV light off the bill and towards a mirror that hits a sensor. White printer paper reflects HARD, due to the fluorescents to make it whiter, causing it to trip

8, at Tue Apr 13 18:32:39 2021 GMT+0700:
Magnetic ink on these machines is just checking for the presence of it
