SignalVault is a real RFID-blocking card sold for contactless credit and debit cards, and its maker says it is designed to block wireless scans when placed in your wallet. The current product page lists a two-card pack, a three-year protection period, and laboratory testing at the contactless-card frequency. Here is what that means before you decide whether it fits your wallet and your budget.

Does SignalVault really work?
SignalVault is meant to sit behind the cards in your wallet and interfere with RFID, or radio-frequency identification, scans. RFID uses radio waves to identify a tag or chip. The seller says its cards use E-Field Technology, need no battery or charging, and were tested at 13.56 MHz, the frequency used by contactless credit and debit cards.
The seller says Qualtest, now N.T.S., tested the setup in an ISO/IEC 17025-accredited laboratory: after the reader was verified, it could not read the test card with SignalVault placed in front of or behind it. A TechAeris review also described a wallet test at a contactless payment terminal: the terminal did not read the card while it sat between two SignalVault cards, then accepted payment after the blockers were removed.
Placement matters. For a longer wallet, the maker recommends one card on each side behind your payment cards, with the logo facing outward. For a smaller wallet or one-card setup, position the protected side outward. This is a wallet accessory, so the useful question is whether your cards have the contactless symbol or RFID chip and whether they remain within the card’s stated protection range.
SignalVault is for wireless card scanning; it is not designed for data breaches, phishing, or a compromised card reader.
What does the Shark Tank story tell you?
SignalVault appeared on Shark Tank Blog’s SignalVault update as a Season 7 business. The report says the pitch ended in a $200,000 deal for 25% equity with two Sharks. It also reports that the company sold out of 4,800 units during a QVC appearance eight minutes long and had passed $2 million in sales in the months following the show.
For a shopper today, the practical update is that SignalVault’s product page is active and offers the two-pack for purchase. Shark Tank Blog reported in January 2023 that the business was still operating and put annual revenue at around $1 million. Those are historical business figures, not a current valuation.
What is SignalVault worth today?
There is no price tag for the whole business in the current shopping decision. Shark Tank Blog reported a $1,666,667 valuation at the original pitch, based on the $200,000 ask for 12% equity. It later reported an estimate of $4–5 million for the founder’s net worth as of January 2023. A founder’s personal net worth and a company valuation are different things, so neither figure tells you what SignalVault is worth today. If that affects an investment or business decision, ask the company for current information directly.
How much does SignalVault cost?
Prices shown October 20, 2026: the SignalVault two-pack page shows a regular price of $20 and a sale price of $25. Because the displayed sale price is higher than the displayed regular price, confirm the final amount in the cart before you pay. The same page advertises free U.S. shipping on orders over $25 and a text-message offer for 10% savings.
| Item | What the product page lists |
|---|---|
| SignalVault RFID Blocking Card Protector | 2 cards per pack |
| Regular price | $20 |
| Sale price | $25 |
| Shipping offer | Free U.S. shipping on orders over $25 |
| Listed coverage period | About 3 years |
What do you get, and how do you use it?
The two-pack is built for either a longer wallet with a protector on each side or two separate wallets. The cards are intended to slide in alongside your existing cards, rather than replacing your wallet or requiring sleeves. The maker says to replace them every three years.
A 2017 TechAeris review described the cards as credit-card sized and slightly thicker than a standard card. It also described the separate TravelVault passport case, but that is a different product from the two-card SignalVault pack.
What about SignalVault reviews and Reddit comments?
The product page displays 648 customer reviews. That number is a seller-page total, so read the recent written entries for details that matter to you, such as wallet fit, card placement, delivery, and support. Reddit posts can add individual experiences, but they do not replace checking the product page’s stated warranty and checkout total.
If you are comparing product-claim pages in general, our steel river colossal fixed blade reviews guide shows the same useful habit: match the item, the price shown at checkout, and the policy terms before buying.
What does the protection guarantee mean?
The seller calls this a 100% Protection Guarantee and says the product protects your information for three years or your money back. The TechAeris review reproduces terms stating that reimbursement for qualifying RFID theft may require a police report and identity-theft affidavit, and applies to charges not covered by your card company or financial institution after proper installation.
If you already paid and need help, keep your order confirmation, the product packaging, and any relevant transaction records. Then contact SignalVault through the support options on its product site and state whether your request concerns delivery, the three-year protection guarantee, or a charge you want explained.
SignalVault versus a blocking wallet, sleeve, or DIY option
| Option | What changes | Best question to ask yourself |
|---|---|---|
| SignalVault cards | You keep your current wallet and add one or two cards behind payment cards. | Do you want RFID blocking without changing wallets? |
| RFID-blocking wallet | You replace the wallet itself. | Do you also need a new wallet layout? |
| Card sleeves | Each card goes into its own sleeve. | Will you consistently use and replace sleeves? |
| DIY shielding | You source and position the material yourself. | Do you want to measure and manage the setup yourself? |
Shark Tank Blog notes that blocking wallets and card sleeves are other ways people address RFID scanning. SignalVault’s appeal is the done-for-you format: the maker says the cards slide into the wallet you already carry, with no charging or activation.
Before you order
- Look for the contactless symbol or RFID chip on the cards you plan to carry.
- Confirm the cart total, since the page’s regular and sale prices are displayed in an unusual order.
- Choose a two-card placement if you use a longer wallet.
- Read the guarantee terms before relying on them for a reimbursement request.
- If you want a broader checklist for assessing a seller’s claims and checkout terms, see visivra reviews.
The small next step is simple: check your cards for contactless capability, then compare the cart total and the three-year guarantee terms with the wallet setup you already use.
