## Abstract

The present invention provides a physical card capable of improving authenticity identification and a method of using thereof. The physical card is provided with two electronic tags of different wavebands. When a physical card is to be traded, the purchaser can perform an appearance inspection of the physical card, or use a first reader in the purchaser's mobile phone to directly read a high-frequency electronic tag of the physical card and obtain a card first information, so that purchaser can quickly and automatically determine the authenticity of the physical card. In addition, an UHF electronic tag in the physical card can be read by a second reader of a verification agency, and then a second information of the physical card can be obtained. Since the physical card is used without leaving the holder of the physical card during the whole process, the contactless transaction mode maintains a social safety distance, which can improve the security of the physical card when in use.

## Claims

### Claim 1

A method for using a physical card, applied to an exchange of a commodity, comprising:
configured a first reader that is used for reading a high-frequency signal and owned by a seller;
configured a second reader that is used for reading an ultra-high frequency signal and owned by said seller;
providing said physical card configured with at least one high-frequency electronic tag for generating said high-frequency signal and at least one ultra-high frequency electronic tag for generating said ultra-high frequency signal to a user;
completing an order of said commodity by the user to make that the user becomes a commodity exchanger;
requiring a staff of said seller to transport said commodity to a delivery location designated by the user;
requiring said staff of said seller to confirm whether the user is the commodity exchanger by using said first reader to read said high-frequency signal generated from said at least one high-frequency electronic tag of said physical card held by the user;
requiring said staff of said seller to confirm whether the user is the commodity exchanger by using said second reader to read said ultra-high frequency signal generated from said at least one ultra-high frequency electronic tag of said physical card held by the user if said first reader fails to read said high-frequency signal; and
requiring said staff of said seller to deliver said commodity ordered by the user to the user after confirming that the user is said commodity exchanger.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising:
requiring said staff of said seller to confirm whether the user is said commodity exchanger by reviewing a plaintext information presented on said physical card held by the user when said second reader has read a plurality of said ultra-high frequency signals.

### Claim 3 (depends on 1)

The method according to claim 1, further comprising:
obtaining an order number when the user of said physical card completes said order of said commodity;
embedding said order number into said high-frequency signal generated from said at least one high-frequency electronic tag of said physical card held by the user;
configuring a first electronic wallet in said at least one high-frequency electronic tag of said physical card; and
deducting a commodity payment from said first electronic wallet of said at least one high-frequency electronic tag when said first reader reads said high-frequency signal with said order number or marking a commodity received message in said physical card when said first reader reads said high-frequency signal with said order number.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising:
configuring a second electronic wallet in said at least one ultra-high frequency electronic tag of said physical card; and
deducting a commodity payment from said second electronic wallet of said ultra-high frequency electronic tag, transferring a certain amount from a credit card to said second electronic wallet when an amount stored in said second electronic wallet is lower than a price of said commodity to ensure that said second electronic wallet stores a sufficient amount capable of paying said commodity, marking a shortfall amount message in said second electronic wallet when said amount stored in said second electronic wallet is lower than said price of said commodity, or paying for said commodity in cash when said amount stored in said second electronic wallet is lower than said price of said commodity.

### Claim 5 (depends on 3)

The method according to claim 3, further comprising:
transferring a certain amount from a credit card to said first electronic wallet when an amount stored in said first electronic wallet is lower than a price of said commodity so as to ensure that said first electronic wallet stores a sufficient amount capable for paying said commodity, or marking a shortfall amount message in said first electronic wallet when said amount stored in said first electronic wallet is lower than said price of said commodity, or paying for said commodity in cash when said amount stored in said first electronic wallet is lower than said price of said commodity.
