Yes, You can show the Taoist Talismans to someone. The fee to create and empower different talismans are at different fees, depending on the complexity of the talismans. More complicated designs are thus more expensive. Attraction and Sex Related Talismans and those Talismans for revenge purposes are the expensive ones.
If You have lost the talisman, nothing will happen to You, just that You won't be protected or blessed by the deities all day long, like how 'it' has been working on You while You are keeping it or praying to it.
If You handle the talisman incorrectly (Example: Any how put and not respecting it), nothing bad will happen to You, just that the deities won't be bothered to bless or help You. However, as a rule of thumb, always respect the deities by placing the talismans on the altar, or keep them inside the drawer when not using it.
The Taoist talismans are ritually empowered with the spiritual energy of the particular deities-in-charge (of the talismans). Therefore, the deities can sense whether You give them the respect they deserved. If not, Heavenly deities will just ignore You.
Important Note: If the spiritual items are ghosts level, such as ghost kids (Gui Kia-鬼仔), or ghosts caught / invited from the graves or places of death, then 'they' will seek revenge or disturb the person or the people who insult 'them' (Example: Deliberately step on the ghost figurines, ghost talismans).
Never ever steal a talisman if it is not free (Or wanted to have a ritual done but don't want to pay the fee)
Most of the public Taoist temples are providing "FREE" Version of Mass Photo-copied, Unempowered (Meaning: Useless) paper talismans to the public. But then, there are also Real "FREE" Talismans which are available at the Temples with Spirit Medium Worships. Howoever, most of the talismans that are hand-drawn and spiritually empowered by Taoist Masters / Sorcerers are NOT FREE, meaning You have to pay for the service charge.

Taoist Masters / Sorcerers spend time, energy and expertise to create and go through ritual to empower the talismans. There are some people who want to own the "Charge A Fee" Version (meaning: High Quality) Talismans and yet don't want to pay for spiritual items, so they would steal from the temples / shops/ altars of the Taoist Masters / Sorcerers. Another type of clients / customers (call them thieves / cheaters) would pay with credit cards and then after receiving the talismans or when the rituals completely done, they will go to the bank to seek "charge-backs", saying those are unauthorised transactions.
Extra Info: There are many stories of worshippers who steal the Deity Statues (due to their efficacious results after worshipping the deities) from the temples but to return back again to the temples, after the thieves were being punished severely by the deities.
What happen to the Taoist Masters / Sorcerers and those thieves / cheaters?
Taoist Masters / Sorcerers have wasted their time, energy and money to create and empower the talismans or on performing the rituals. The thieves / cheaters will be punished by the deities or ghosts themselves (even without the Taoist Masters / Sorcerers involved), in which the outcome will be much worse off than being HIT by Black Magic (Gong Tau - 降头).
If You are in the wrong, engaging other Spiritual Masters to protect You from the punishments of deities and revenge by ghosts is wasting Your own time and efford because the Spiritual Masters can't help You in this kind of situation and will only advise You to return back the stolen spiritual items or go back to the origial source to do prayer to ask for forgiveness.
Some typical examples of punishments:
- Suffer various kinds of Sicknesses ( punishment by deities or ghosts)
- Losing lots of money for various kinds of reasons (punishment by deities or ghosts)
- Disturb by the ghosts
- Involved in Accidents one after another (punishment by ghosts)
- Disability (punishment by ghosts)
- Death (punishment by ghosts)
Revenge by Taoist Sorcerers
Not only punishments meted out by the deities or ghosts, Taoist Sorcerers might do their part to seek revenge as well. Often time, Taoist Masters who practice only positive magic will leave the punishments to the deities but when come to Taoist Sorcerers, who know the secret magic spells of Black Magic, will call upon '5 Ghosts' or wandering spirits to disturb and create havoc on the thieves / cheaters. This will be double whammy to the thieves / cheaters.
Extra Information but still important: Some people would promise the ghosts that they will do certain amount of offerings to 'them', if they (the worshippers) would win certain amount of money from winning the lottery (usually 1st Prize) with 'their' help. Once the winning is achieved, the winners take the winning and forget to return the offerings (Example: not returning the favor of burning certain amount of joss papers, or do spiritual-transcending ritual for the ghosts). Sometime, death due to accident is the result caused by the ghosts.
