Identify playing cards from the back : recognize the 54 playing card

扑克是一种休闲工具，全国各地，每个家庭都知道，无论是工人，农民，学生，政府官员都愿意利用业余时间玩，在这种情况下，如果我们成功地展示识别扑克牌回来，魔术会被人们所喜爱。

死的工作

We all know that magic is fake, and the poker we bought needs to be processed by ourselves. First of all, we should choose the poker which is easier to mark. The best thing is to buy a pair of red-backed circus poker. This poker is easy to mark and fast to recognize.

Making tools

1. Women make fine needles for needlework.

2. Red ink paste used for seals and famous seals.

Making method

Make red dots on the back of the poker with fine needles and red mud. Make the mark method and position in detail. See the illustration of circus poker.

The circus poker and illustration illustrate the following:

As you can see from the graph, if the red dot represents A in the first lattice and 2 in the second lattice, by analogy, this method can be flexible to patrol so that you can get out quickly.

Note:

1，这个马戏团扑克的背面必须是红色的，因为我们用于标记的红色墨水是红色的。

2，红点必须更小更好，这样才能识别它们。
